Createk (spelling) is what i use for airbrushing/custom paint and for pinstriping i use 1-shot.. being that i am new to custom painting i havent tried many products.
I havent painted a full car yet (access to a spray booth is a bit unatainable) but hopefully with in the next few months i will be able to get into one...
Shoot, i can try to help as much as i can.
