I have 3 guns 2 are devilbiss. one pint gun [ I would call it a touch up gun] it works great for spraying color. the second gun is bigger I use it for clear.I only use the big gun for spraying clear lacquer.
I just bought a top feed gun from harbor freight and it works great 39.00 sale price 16.00
the compressor is a emglo model Emglo AM99-HC4V 2 Horsepower 5.6 CFM Compressor
Yield 125 PSI with air line regulator with twin tanks
small but enough to spray finish all day long and use a nail gun when I need it put new shingle on my house.
looking on Amazon dewalt has the same kind for 250.00 with free shipping.
I spray using 35 psi. make sure your gun is clean and free from dirt and old finish.
