No, I dont do it anymore. The kits above are better deals anyway.

Ok, I asked the guy that I do custom work for. He is a professional model builder. He also restores real cars. You need to buy a Du Pont product called Prep Sol. You will have to buy it from a auto body paint shop. It's about $50.00 for a gallon. He has been building resin kits for many years now. He told me that today that the quality of resin kits that a lot of casters is just worthless. He has people send him kits to build and the surface is impossible to even prep to get paint on it! He said it seems that somehow mold release is somehow absorbed in the resin part also there are a lot of fine tiny holes. He got a kit and it is rubbery and it is junk. It came from someone in Tennesee. Some bodies are very thick and a lot of work goes into opening up window openings and pillars and then after all that time consuming sanding and filling windows don't fit right. Having a vacuum chamber and pump is a must have items to make good parts. I vacuum my resin down before I measure and mix the two parts together. Vacuuming or de airing the resin will remove moisture from it. Then I pressure cast the mold with weight on top of the mold. This helps create very thin flash around the part. I spray mold release in the molds but then I let it set for a few minutes for the release to gas out. Spraying release on the mold and making a part right away will cause parts to be rubbery and not cure correctly. There is a lot to know to make good parts.

Not that I know of.

I have one of these mint Mod Squad kits.

OK, I called this company and the wonderful lady there is sending me free sample cans of this and a EMI brand A479. Both are are non silicone and food grade rated as well. I should get them next week and I will do some product testing.

https://www.emicorp.com/item/ME+514E/A514-Zip-Paintable-Food-Grade-Mold-Release/ I'm not certain why as resin casters of model car parts that need gluing, painting and plating why we don't use a product like this. This product seems to be a good match for what we do. The biggest hurdle of the process is making a two part mold. The release is really important to make certain the two different pours (top half and bottom half don't bond together and become one mold trapping the parts inside. Having to do surgery with a exact knife to hopefully cut the mold up with enough care as to not ruin a rare part.

I had not thought about discoloration since I have not actually tried it. I suppose it is ironic that I know how to make nice resin parts but dont know squat about prepping them for painting. I do have some mold release that is paintable and food grade. If casters would use that then all the worries would not exist for prepping parts to paint and build.

Gotcha, I can still make them.

It seems bleachwhite is popular but I'm not sure why purple cleaner won't do the job. It is a strong degreaser. I use Zep brand from Home Depot to remove chrome from parts.

You can also get these nice grilles. The headlight detail is very good.

Nice work

Hi, Send a email to: hgresin@gmail.com and Marty will put you on the list. Covid has caused some problems. We got the 4 door Lemans from Dwayne. It is a nicer kit than this Crown Vic. I have the body mold done., but many more parts to do. Thanks, Greg

Nice work.

I found this book in a stack of folders I had never looked at since moving here and working in the shop.

You should purchase the the kit in another topic here. It is a more complete kit than what I make. I am more interested in doing the four door police cars for Dwayne L.
