No flame suit needed, you did described it correctly in that instance. Waterbase does need alot of air flow and more time to dry, which is why there was alot of huss and fuss in big get them in and pump em out shops about it. The argument was that it would cut down on production, people would lose money, the material actually was going to cost more and the booths needed to be retrofitted with high volume fans. Not really fans, more like little nipples that move tons of air. We had them installed in our booth for when the mandatory switch comes to our state. They move a buttload of air and do the job they are supposed to. But man they were expensive. Water base definitely has its advantages to the environment. cause every car has a color that will no longer have solvents in them, and the painter as well. Heck if you mess up, just wipe it right off with a spray bottle and a towel and start over again. I dont particularly like it cause it doesnt seem to lay nearly as well as solvent based paints. I figure cause water is the heaviest liquid around so it doesnt quite atomize as easily. The color matching seems to be more volatile to me but getting that down will come with more experience. During the sata training they were telling us wed need to buy seperate guns, that any gun that had solvents ran through it would have to be kept seperate from waterbase. Just a ploy to get you to buy more guns I guess cause as long as you clean your gun well and let the thinner evaporate out of there, get some air moving through it. No reactions or anything so far. Ive only used waterbase a few times, were still spraying solvent base dupont chromabase system. But when the mandatory switch comes well have to suck it up and do it.
