As far as PSI, higher pressures work with HVLP but 50 with an RP is too high. Every painter shoots differently even using the same gun. Some like close(4-5") and fast, and all wet coats, no tack coat. I don't shoot tack coats and I'm not alone. Whatever works for each, as long as the outcome is good. If a clear calls for a minimum mil thickness on the TDS using wet coats, a tack coat is a waste of T&M or it will reduce the recommended mil thickness. Full wet coats as shown on a TDS will not lead to runs if shot properly.
This is a very well said post. The line of clear that you use, has a lot to do with this pole; as does the catalyst, ambient temp, type of job, humidity, etc. I'm assuming that he was asking about the run of the mill quick clear that most people seem to use on your average job.
Some production clears can be cut in as little as 2-4 hours, but i dont think thats what the majority of folks on this form use. I own a shop, and I never use that kind of clear.
And you are absolutely right about painters and there techninques, everyone has a different style. As you are about Compliant guns, they're just as different from HVLP's as Conventionals are. Very well said post my friend.
