sonictherevenge Posted February 25, 2014 Share Posted February 25, 2014 Just wondering if you all wet sand the primer all the time. I just re primed the car and it looks amazingly smooth as is but should I go ahead and wet sand anyway.. I am going for a very smooth show room type finish.

GeeBee Posted February 25, 2014 Share Posted February 25, 2014 Years ago I never bothered, but I do all the time now, looking back at some of my older builds you can see the difference in the final paint finish Quote Link to comment Share on other sites More sharing options...
LoneWolf15 Posted February 25, 2014 Share Posted February 25, 2014 The smoother the surface to be painted , the smoother the paint finish will be ! Quote Link to comment Share on other sites More sharing options...
sonictherevenge Posted February 25, 2014 Author Share Posted February 25, 2014 I normally use 800 to wet sand should I use another grit ? Quote Link to comment Share on other sites More sharing options...

LoneWolf15 Posted February 25, 2014 Share Posted February 25, 2014 I take mine all the way up to 12000 . Yes , the paint will stick , I promise ! Again , the smoother the surface , the smoother the finish ! Quote Link to comment Share on other sites More sharing options...
BKcustoms Posted February 27, 2014 Share Posted February 27, 2014 What type of paint are you using? If it's Enamel Donn's method works great! If it's automotive paint (urethane) sand with 800-1000 grit, I've had issues with it not sticking that well when I use anything finer than that.

Art Anderson Posted February 27, 2014 Share Posted February 27, 2014 I've "polished" the primer on every model car I've built since the first Micromesh polishing kits were marketed by Tom & Linda Gaffney (LMG Enterprises), back about 1980 or thereabouts. For "polishing" primer (I still prefer using automotive acrylic lacquer primer) I use a Micromesh 6000-grit polishing cloth with water--think of it as wet-sanding primer in scale. My philosophy? The smoother the plastic surface, the smoother the primer, the smoother my paintjobs come out, meaning a lot less polishing after the finish coats are applied.

Baugher Garage Posted February 27, 2014 Share Posted February 27, 2014 I've always been intimidated by trying to paint anything "shiny" but these tips might give me some courage! Quote Link to comment Share on other sites More sharing options...

Bandit17 Posted March 4, 2014 Share Posted March 4, 2014 I have a similar question, which grit sandpaper should I use to wet sand the color before I clear coat? Quote Link to comment Share on other sites More sharing options...
