First off--you probably reduced (thinned) the paint too much for spraying, and didn't put enough on the object! If you go to painting with hardener, it won't make much difference, if you thin the paint as much as before! It'll still look dried out. Go on down to the local auto body shop. Ask them for some parts like a hood and fender, take them home, and practice spraying those places on them, with small amounts of paint/ thinner, in masked off areas. Mask off small areas with newspaper and masking tape for your practice areas. When you get the right combination of paint/thinner/air pressure, try that on your parts, then you'll know how to get the correct look from your work! Another tip is to hold the spray gun perpendicular to the surface, so you get aneven coat of paint! Too many inexperienced fellows spray in an "arc", and the end result is too much in one place, and not enough in another! Then they go back and spray over it, and get runs and sags in the finish! I have found that 45-55 lbs. air pressure is usually high enough for painting. If you are using an air compressor with a small tank and low cubic feet per minute, you'll probably have to wait every so often for the compressor to catch up. And, if you are thinking about buying an air compressor, just remember: They'll all pump up to 125 lbs. or so! But its not about pressure--its cubic feet per minute! The higher the cfm, the longer you can spray or run air tools before the compressor comes back on. The lower cfm will not be suitable for air tools--it won't keep up--you'll run out of air, and probably burn out the motor! RJ ps: any ?. E-me
