|I shot 6 liters and have an average thickness of 50-60mils (1/16", 1.27mm).
First coat - 3 liters for coverage.
Second coat - one hour flash time and then 2 liters to build up previous coat. The first two coats had nice texture but were smoother than factory.
Third coat - to experiment with textures and "find"a nice finish. I fogged (drop coat) most of the last liter after 18 hours flash time onto a still-tacky gooey surface. This coat formed primarily on top of the 2nd, instead of melting into the previous coats. This looks far better. Since I only had one liter, I concentrated on the more visible areas first and then worked my way out.
Looks like giving a good period of time between coats for solvent evaporation can help attain a high-relief texture. "Flash time" of course, depends on temperature and humidity. Karmann certainly used more product than 6 liters.
