AgRacer Posted January 6, 2014 Share Posted January 6, 2014 Howdy, New here. See http://www.modelcarsmag.com/forums/index.php?showtopic=83804 Had this one partially complete in the box so decided to finish it in Yellow. Just ordered some ScaleFinishes paints. Never used a basecoat/clear method. I've always used either airbrushed enamel gloss paints (testors MM) or Tamiya TS Sprays to do my cars. Built a new paint booth to replace my old dirty one... Made from leftover 3/4 Melamine and a corrugated plastic backing and baffle. Fan is a 545cfm Dayton blower. I just open the window and trap it in the window when I paint. Haven't even used this one yet. My old one was scraps of decking boards. The white interior makes things much brighter and the baffle should control air flow much better. Never done flocking before. First attempt...kinda so so.... I'll have to practice this some more Parts and pieces The dash needs some touch up. Body will be Ferrari 102 Giallo when it's all done.

AgRacer Posted January 10, 2014 Author Share Posted January 10, 2014 Sanded all the body parts seams and used some Mr. Surfacer 1000 and sanded again. Waiting on the Scalefinishes paints to arrive so I can primer and start painting the body. Quote Link to comment Share on other sites More sharing options...
kendog261 Posted January 10, 2014 Share Posted January 10, 2014 Looking good so far. Try this link for some tips on flocking it really helped me a lot http://italianhorses.net/Tutorials/Flocking/flocking.htm Quote Link to comment Share on other sites More sharing options...
AgRacer Posted January 11, 2014 Author Share Posted January 11, 2014 Yep, I know about Alex's page. I just did not think to look. My problem was I did not sift the flocking...and it's like 10-years old!!!! Like I said, it's been awhile since I've built anything. Masked the windows tonight and cleaned the lower body work and some other bits that will be painted black. Side windows. The Tamiya masks were not a perfect fit so I used some liquid masking film to fill in and also do the outside window. When it dries I'll trim with an exact-o to get a nice edge on the rain lip on top of the windows In the spray booth cleaned and ready. Why is the bottom part clear and the instructions tell you to paint it X-18...??? My son's is building an Enzo on the table I set up for him....thanks Santa!

niteowl7710 Posted January 11, 2014 Share Posted January 11, 2014 In the spray booth cleaned and ready. Why is the bottom part clear and the instructions tell you to paint it X-18...??? The option exists to either paint it black like the real car, or leave it clear so you can see all the work you put into the engine and transmission which would disappear with that defuser in place and opaque.

AgRacer Posted January 12, 2014 Author Share Posted January 12, 2014 Painted the under body and windows. The liquid mask worked great on one side, but for some reason it was a bear to get off the other side of each side window. I had to 'scrub' it off with a toothpick. Still some work to do (those little black specs on the windows are liquid mask stuck on plastic. New paint both worked really well..no fumes in the house at all. Even spraying lacquer to clean the air brush...not smell at all. Pealing off the mask Quote Link to comment Share on other sites More sharing options...
countach79 Posted January 12, 2014 Share Posted January 12, 2014 Nice How do u find the liquid mask? Any good? Quote Link to comment Share on other sites More sharing options...
AgRacer Posted January 15, 2014 Author Share Posted January 15, 2014 Local hobby store had it. You can also find it online. You can apply with a brush, let it dry, then cut out where you want paint. It makes a nice tight seal and no bleed through. I started using it many years ago for airplane canopies. I just coat the whole canopy, then cut out along the frames. Much easier to use than masking tape. A little bit of dry fitting parts. This showed up today! heat shield... Quote Link to comment Share on other sites More sharing options...
AgRacer Posted January 17, 2014 Author Share Posted January 17, 2014 Got the primer coat on today. It goes on very thin. At first I did not think I mixed it well enough. It is a very thin and fine pigment gray primer. I put ~4-coats, waited 40m and put on the white sealer. Put on 3-sealer coats and let it dry. After it was dried, I saw that I did not sand down the Mr. Surfacer well enough and it was showing through the white sealer and would look lumpy when I put on the base. So I sanded down the hood tonight and put on primer and sealer. It will dry overnight and I'll start the base coat tomorrow. Primer Sealer coat. You can see the Mr. Surfacer in the hood.

AgRacer Posted January 17, 2014 Author Share Posted January 17, 2014 (edited) I'm not sure what type of paint the primer is, but I had a heck of a time getting it cleaned out of my airbrush. I finally got it with testors airbrush thinner. I also learned you have to keep mixing the paint as the pigment falls out very quickly. I loaded my color cup in the Paasche dual action, and while I waited 5m between coats, the pigment fell to the bottom of the cup and clogged up the intake tube. LESSON: For Scalefinished Primer, after you paint, you need to keep stirring the paint in your color cup while you wait between coats. The primer will clean with testors airbrush thinner (#1799). The while sealer coat is an enamel type paint that cleans with lacquer thinner from the hardware store.

AgRacer Posted January 18, 2014 Author Share Posted January 18, 2014 (edited) Put on the base coat tonight. I was going to do yellow but found out the Ferrari Gaillo 102 is a pale yellow, not the bright yellow I wanted so this one will be red. I'll do my Enzo in Yellow. My Eduard Photoetch Cockpit set arrived for my 1/32 Tamiya Corsair and I want to get that started ASAP so i didn't wait for the yellow...oh well.... Coat 1 Coat 2 Coat 3 Clear Coat x3 Wait for 24 hours to dry then polish and finish assembly. Edited January 18, 2014 by AgRacer Quote Link to comment Share on other sites More sharing options...

LacrosseBoss Posted January 21, 2014 Share Posted January 21, 2014 Looks great. The red is turning out awesome, but I'm also a big fan of yellow cars, especially Ferraris. Too bad! You mentioned your paint booth. Can you show a picture of it? What booth are you using, or did you custom rig something? I live/model in a basement apartment with minimal ventilation so I've been looking at a better option than standing in the stairwell with the door propped open ....

AgRacer Posted January 21, 2014 Author Share Posted January 21, 2014 I started to polish the paint and it just looked terrible. Their was just to much texture in the paint finish. My fautl, I guess I just did not get a smooth coat of gloss down on the model so it came out with a lot of orange peel. I tried to polish but I could never get it to smooth out. Airbrush was too far away from the model (I'm guessing) when I put down the gloss finish. That, and the Mr. Surfacer was really showing through making the hood and roof look terrible. So I'm in the process of stripping the paint off and starting over. The gloss coat came off in layers (litterally peeled it off). Hopefully tonight I can get the rest of the paint off, get the body cleaned up and start again. I ordered the yellow and if it gets here by Thursday I'll paint it yellow. Matthew - My paint booth is a simple box made of 3/4" Melamine with a corrigated plastic back (to let more light in). I used corrigated plastic to make a baffel at the top (that piece at the top inside at an angle). I have the fan mounted on top and the baffle pulls more air from the work area. If I did not have the baffle, the fan would pull a lot more air from the top of the opening and kind of bypass the lower part where the actual painting is done. The fan is a 500CFM Dayton blower. I cut a hole in the top, glues some foam matting around the hole as a seal agains the fan, cut up an HVAC filter and put it between the fan and the foam. The fan just discharges to a 6" flexible duct that I blow out the window. Quote Link to comment Share on other sites More sharing options...

AgRacer Posted January 22, 2014 Author Share Posted January 22, 2014 (edited) Just be sure and buy a large enough fan. The box can be made of anything, but the melamine gives a nice clean surface. I used 3/4" b/c I had some left over from a garage work bench. You could probably use 1/2". HD has a 16" x 72" piece for $30. The corrugated plastic was $5. you wan the air velocity at the opening to be >/= 100 feet-per-minute. Example, My booth is 12" high by 18" wide at the front. So 1ft x 1.5 ft = 1.5 square-feet. To get 100 feet per minute, I need 1.5 ft^2 x 100 ft/min = 150 ft^3/min (CFM) So I need, at a minimum a 150 CFM fan...but you actually need more. There are pressure losses in the system (hood in, fan in, fan out, flex duct) that add to the static pressure requirements for the fan. So the fan needs to be RATED for 150CFm at the static loss. Probably close to 2" when you add it all up. The home depot bathroom fans and in-line fan are not enough. NOTE: Home-Depot sells a "250 CFM" in-line booster fan. That fan is NOT 250 CFM. It is 250 CFM if there is already pressure behind the unit. It's designed to be mounted in an existing HVAC duct and boost air flow to a room. As a stand alone unit, it's only rated for 160 CFM and ZERO inches of pressure loss. It won't be near enough for your hood unless it's very small. I used a Dayton blower (found at Grainger) rated at ~545 CFM at ZERO inches of static pressure. Those units are $200 now. Just FYI for everyone. A bathroom fan really won't do anything to remove fumes. You need a good fan, and respirator. http://www.homedepot.com/p/Unbranded-3-4-in-x-16-in-x-72-in-White-Thermally-Fused-Melamine-Shelf-57199/203806543 If the hood is 12" High x 20" Long (12 + 12 + 20 + 20 = 64" < 72"). I used some 1-1/2" long #8 wood screws to hold it together (pre-drill the holes). This will give you a 16" x 20" work surface. http://www.homedepot.com/p/Plaskolite-18-in-x-24-in-Corrugated-Plastic-Sheet-1TW1824A/202043334 Glue this to the back side and use a box cutter to cut off the excess. Use the extra as a baffle inside the unit. Seal everything with some silicone bathroom/tile sealer. THIS Fan will not work well enough. http://www.homedepot.com/p/Suncourt-Inductor-6-in-In-Line-Duct-Fan-DB206/100067594 Edited January 22, 2014 by AgRacer Quote Link to comment Share on other sites More sharing options...
AgRacer Posted January 30, 2014 Author Share Posted January 30, 2014 Got the old paint off and put on a new basecoat and clear. Polishing has started. Taking a while to get it all smooth. I've learned that the first polish cloth is really the most critical. I saw an example where some guy used a plastic spoon and showed how to get a good shine. I realized that I've been using the polish all wrong and if I do not get that first cloth done and all the paint looks dull, the remaining polish cloths leave those 'gaps' there and it looks terrible. When I get a chance I'll upload some pics. Quote Link to comment Share on other sites More sharing options...

AgRacer Posted February 11, 2014 Author Share Posted February 11, 2014 OK, I'm still working. Just that real work got in the way. Got the body repainted and polished. This really my first full polish attempt. Micromesh 3200, 3400, 4000, 6000, 8000, 12,000 and then Meguires Scratch X 2.0, then Rubbing Compound, then Modelers Final Detail Wax. It came out OK. You can still see some micro-scratches in the finish and I got thru a few places to the paint (need to make sure my primer is smoother before I color coat).
