any tips and help from pros would be welcome! thank you
the way I was taught was "practice on a piece of something (steel pipe is GREAT for frames) till you can shoot it with NO ORANGE PEEL", then you don't need to color sand (which you really can't on a matte finish)

matte finishes are shot differently than gloss clearcoats, it's more of a gradual build-up, instead of trying to shoot full wet coats, I typically shoot 7 to 10 mist coats when shooting matte finishes, where as with a typical clearcoat, usually your done after two full wet coats.

seriously, you really cannot sand a matte finish without topcoating it again, and if you shoot with peel, you'll be doing the sanding/shooting forever.

if you have peel, your gun isn't matched to your compressor (gun uses 18cfm and compressor is rated at 7cfm VERY COMMON!), or it's not adjusted right*, AND your trying to apply too much paint at once.
also try using a DETAIL GUN for shooting matte finishes or frames, as the 3" fan pattern makes getting the tubes even a snap, and with a detail gun you will be forced to shoot more coats as it wont put out anywhere near the paint volume of a standard paint gun (and you SHOULD be using at least a HVLP, with the newer LVLP guns being my first choice)


PRACTICE, PRACTICE, PRACTICE


(* runs are a FLUID adjustment (you need less), and peel is an AIR adjustment (you need more)
