30 minutes seems too little to me even for the spray can, but just to clarify if you guys use regular 1 gallon 2K clearcoat it costs about $100-150 for the cheaper stuff and has a shelf life of I think a few hours, maybe 2-3, but yes for the most part use it within an hour would be better. if you thin it ,which some people do not know about, you can thin it ,however I wasted several thousands of dollars on bad advice from the ignorant sales lady at the paint store. there is a brand in a yellow can which has a chemical in it like paint stripper, it causes adverse reactions to other paint brands if you use it. this was a problem that spanned several years so to make it short, try to use valspar or other quality brands. also if you can do not use PPG basecoat and for clearcoat the best deal is tamco paint. their clearcoat is like 2-4 times cheaper than any one else's but the same high quality also the thinner used needs to be in the same brand line, you simply use the reducer, the same product used for the basecoat reducer

I've been learning about painting cars for a while so I know the basics. There's a lot of misinformation here. #1 yes this is for professional use so anybody who didn't know you need an organic vapor rated respirator with unexpired cartridges should not be using 2K paint. Those cartridges DO HAVE a limited number of hours of use depending on your climate. put it in a ziplock when not in use to extend the life. The clearcoat will enter your lungs and will cause massive damage. That's not the worst of it, 2K paint has a chemical in it (I forgot the name) but it's basically like radiation, if you breath in those fumes enough without proper ventilation or filtration you will literally drop dead from accumulation. And yes you need proper ventilation as well as you should have a proper spray booth to minimize the dust on the finish, but for modeling I don't know if you can get away with not using one. Anyways the problem looks like an adverse chemical reaction from whatever basecoat was underneath the clearcoat. Spray Max 2k is the only spray can I've heard of that's equal to real 2K paint from the automotive paint store. it's always smart to create a test panel, go to any hardware store and take some sample paint color cards or get some from the auto paint store. you could also use any magazine or packaging that has graphics on it because they usually have colored ink on it that would work, you don't want to use anything porous like printer paper, something flat textured and non-porous would work. also 2K has a finishing step where you wet sand the clearcoat with a high grit like say 800-3000 grit and using a polishing cream like meguiars. there's also a flattener you can mix with it to get a flatter finish. Anyways please don't mess with this stuff unless you do proper research. I think 2K should be superior to whatever you guys use normally at least for metallics because unlike your normal paints 2K has metallic flakes in some paints and the hardness is harder. 2K also has the option for candy which is just the basecoat and clear mixed, but I'm sure you could do that with normal paint. actually the metal flakes are sold separately too so maybe you can mix the flakes in with your lacquers or acrylic paints you guys use. also you could have stripped the whole thing using "aircraft stripper" , the hardware store also has strippers that will work but I have tried many and only a couple are able to actually strip 2K . the best one I remember was from "kleen strip" I think it was called

No it won't 2K clear has an activator, alcohol will do very little to this type of clearcoat
