Yeah, time for me to buy an airbrush set and get some Zero primer, paint and clear. This should keep me free of such troubles. :s

SAME FRIGGIN THING HAPPENED TO ME NOT LONG AGO WHILE I PAINTED HASEGAWA TOYOTA 2000GT with this gold chrome paint from RJ London from singapore i got for like only 3usd~

Is that Auto K lacquer a real cellulose lacquer? Real lacquer is contraband in California now and in lots of other places too. And it has the inherent disadvantage of being very "hot," that is, it reacts with everything.

It's almost certain that Duplicolor primers and clearcoats are synthetic lacquers, which are not compatible with the real thing.

There are plenty of great synthetic lacquer (Tamiya, MM Lacquer System) and urethane (Dupont, PPG, Zero, HOK) bases out there; maybe try one of those next time?

By the way, urethanes and synthetic lacquers are compatible with each other and with Duplicolor paints, and you can even use syn lacquer over enamel!

Science marches on.

It's not specified.
All I know is that is a dedicated automotive lacquer, comes with the name and the code of the original car manufacturer color on it.

Try a process of elimination:

• If you can polish the color coat, it isn't urethane and could be real lacquer or synthetic lacquer.
• If you have to mix the color with a hardener, it's urethane.
• If you can apply it to bare plastic or enamel without damage, it's probably synthetic lacquer. (I don't know whether you can apply urethane directly to plastic, but I don't think so.)
• If you can buy it off the shelf in California, it's not lacquer. (I've heard that some people are actually smuggling lacquer in from Nevada! But legit paint dealers won't touch the stuff.)

I checked on Peter Kwasny GmbH's Auto K Universal and "Effect" spray-can paint. Two things strongly suggest that it's some variation on nitrocellulose (real) lacquer. One, it can't be applied directly to plastic; Kwasny sells a plastic bonding agent that has to be applied first. And... the binding agent base isnitro combination resin.

Given that, I would NOT use the Auto K paints except with other Kwasny products, specifically his plastic bonding agent, primer and clear-coat.

With so many other good paints out there, why risk it?

I think you are right, it's a real lacquer. I used it the very first time on the F2000 directly on the bare plastic and it seemed to etch the plastic a bit (I only used very light coats at the beginning, it also did polish out quite well.

Bought it in France, so I don't know if one can or can't find it on shelf in California.

I did use it cause I have around 20 of them paint cans with excellent color choices.
I might buy the other 2 products from them if I ever need one of these colors again.

Thanks for your help, I appreciate it.
