I have done a lot of RATTLE can painting on small parts, and have learned to READ the label before buying. I first look at what it says about RECOAT TIMES, if it says, WITHIN AN HOUR, or AFTER 24 HOURS, well I try to stay away from using that brand. I also always spray an extra piece of scrap, so that I can recoat, or spay clear to assure no issues pop up. I like sprays that say, RECOAT ANYTIME.
I went on a tour of a high end custom shop, and I asked the owner, " DO YOU EVER USE RATTLE CANS?", and he said ARE YOU KIDDING ME, NO....., well later in the tour we walked by a room and there were dozens and dozens of rattle cans. We all looked at each other like what a liar.
