Hello,I am being to spray on aluminumI have a good amount of experience sprayingI have repainted quite a few cars but spraying acrylic enamelAnyways, I have a hvlp devilbiss topcoat and a hvlp devilbiss primer gunI was told all I need at the paint shop was the wash primer and the polyurathane paintI have never sprayed polyurathane and I feel this is where I am strugglingI spray the wash primer, just a light coating (still transparent), and then wait approx15 minfor it to flash, then spray my topcoatI seem to be having issues with orange peel, or the paint gathering in the curves of my aluminumI am unsure if I am spraying my primer wrong, prepping wrong, or my topcoat wrongFor prepping I clean with thinner, then use a prep paint cleanerThe psi I am running is 20Most aspects of my spraying and prep were given to me by the paint shop, any additional comments would help immenslyThanks In Advance!
I don't know what switches you refer to, but aluminum is a conductor of electricityPlastic, or a match stick are not conductorsPaper clips, unless they are plastic coated, are good conductorsStill don't know why aluminum foil would be used, as it melts really easily.
You might try roughing up your surfaces with a 400 grit body paper, then after your first coat dries completely, go over it with fine grade steel wool before you shoot the poly.This gives both applications a surface to adhere to, and as long as you dont over spray, it shoud turn out perfect.
