How's the flow out for Spray Max? Does it self level pretty well? or do you choose between drips and orange peel? Are you guys leaving it off the gun, or rubbing it out?
If find some urethane formulations react unfavorably with sunscreen. They get soft and basically dissolve, which makes me wonder if anyone has had any problems with Spray Max 2K. In socal, this is an issue, as sunscreen is required most of the time.
Although it breaks all sorts of rules, if you know what you are doing sometimes lacquer can be sprayed over very well cured old paint. It dries very fast and levels out well. This was done sometimes in the old days. The danger is that it can crackle. Fat over lean and all. Using instrument makers lacquer might ameliorate this tendency somewhat.
