hi guys,
if you get mottling then say you clear the car....how can you determine what actually caused the mottling? striping seems straight forward, but how do you determine if you applied the base too dry, too wet, maybe the air pressure wasn't right, etc? When I first started out I'd spray basecoat way too dry causing a gritty surface and it would mottle, and it seems like i've never put it on too wet to cause it, but how can you determine what's actually happening in the base? Are the flakes supposed to stand up, lay down?
Also for drop coats I've seen people not change air pressure but just move back from the panel, drop the air a few pounds, and I've also seen people raise the pressure....what's YOUR best procedure from experience? When I went to school they said lower the pressure and come back some to get "bigger droplets" but i never understood how that technically effects the metallics causing them to lay even.
Thanks in advance!
