I generally allow 15-30 minutes to set between layers in room temp if not slightly higher temps(not too humid). For drying to be ready for bashing, I'd allow at least a full 24 hours after applying the backing or final coat.
i used spaztix color change it dries fairly fast . i sprayd a few thin coats on my hurst body then when it was dry i went over it with gloss black. i love it it changes so many colors. gold'green'copper'orange'red'purple. seems every time you walk around it and look at it you find a new color. love spaztix paint. i also used jackal hobbies internal paint transfers for the grim reaper decals. fit the car i think.was only the secong body i painted. heres a few pics to give you a idea what the paint your going to use might look like.just take your time and go slow good luck.happy bashing.
