Well, the good thing bout it is, you can't even see the top of the cage........to close to roof of cab........I'm jus bein picky and want paint up there........most caged vehicles don't have any paint at all up there.Yeah, definitely do a test panel first. According to what size needle/nozzle combo he's runnin' in the brush it might not spray metallic colors well even when overreduced by 100%. Don't mean to wreck yer plans, just want you to know up front that it might be tricky.
Think what I'll do is airbrush the cage top, best I can then shoot the entire interior right after that, should be able to bury what doesn't look perfect........I hope.
