do i need a moisture trap when painting with water based paints?also what is the best to thin wa paints with?
James I have allways been told you do butI have never used one with water based and have had no problems.As for what to thin your water based paint with I use Isoprpynol(RUBBING ALCOHOL).With out a moister trap you could get some spitting I guess but Ive never seen any.
The type of paint you use has nothing to do with moisture that may accumulate in your compressor tank or air line. It developes when your compressor compresses the air it takes in. The more humidity (moisture)in the air, the more moisture available to be squeezed out of it. The last thing you want to happen is to have a bunch of accumulated water spit out of your airbrush and ruin a paint job (Murphy's law dictates that this will always happen just as you are about to finish the job)! A moisture trap, either on the compressor(preferable), or in the air line, is a small investment. You can thin water based paints with acetone (very flammable), or either isopropyl or denatured alcohol.
