Liquid mask works best for all the nooks and crannies they are designing into today's bodies. Painters be damned. But it takes some patience and or a heat gun, along with 3-5 coats, depending on how thick you put it on. Without allowing it to puddle.

Hope this helps.

I can't get the nicer designs like the air brush guys but it's cheap and it's easy.
