I bomb with rusto so if I'm lucky I got some primo fats handy, if not I'm fucked. I got the standard ny fatty for the kilz
ive always used stock caps cuz i could never get an adapter. But a good friend sent me an aluminum adapter and some ny fats havent tried them out yet.
man just what you do is rock up to the graff shop or find one online just buy an assortment of all sorts of caps generally go from super wide to super skinny and test em out! no set caps apply, it's like asking an artist what paintbrush he uses it all depends on the individual
