I’m putting this in Tips, Tricks, and Tutorials because I’m not sure where else to place my observations/frustrations/questions. When I was young (way before the internet or access to model magazines), I discovered the hard way most spray paints that weren’t Testors or Pactra, wouldn’t be compatible with styrene, and ruined some kits. I do mean ruined too, you might be able to get the paint off, but the plastic is wrinkled forever. So, unless I wanted a smooth custom body from sanding all the wrinkles out of the plastic, I had better get another kit. It only took a couple of ruined kits out of my meager allowance to never attempt alternative paints. In the ‘80s as an adult, I discovered I needed a primer under the topcoat to prevent a wrecked model. PlastiKote was my go to primer for a long time. The only consistent problem I’ve ever had with this method, was ghosting from the flash and parting lines that was sanded off. I know I could try silver paint as recommend as a barrier, but was reluctant due to past problems of paint lifting off silver paint. So, back to my reason for this topic in the first place.
I still see multiple posters on this forum who paint their cars with non-polystyrene compatible paint, but no one ever makes comments or suggestions on this problem. I don’t make comments because, well I don’t build so much anymore and feel it’s not my place to criticize other builders. I will show an example of what I’m talking about.
It’s from a quick build I did of Challenger a few years ago. The paint I used was some auto interior vinyl dye. I had used this brand and color before on other kit’s interiors and chassis’ without a problem, but as you see, this one went funky. I don’t spray heavy coats. My first coat is always a mist and I allow it to flash off before I add several light coats until it is covered. I noticed it was wrinkling after the first light coat, so the damage was done. Fortunately, it was the chassis and interior.
What I hope to get out of this is: a) what are people using for primer, b ) I worked at parts store that sold PlastiKote for years, but now sell Duplicolor and in my experience, it’s not as good so, my question is where do I find PlatiKote primer, c) Has anyone used acrylic floor wax as a primer, and how did that work out?
