On the two bodies with thin white lines I used Pactra Flexible masking tape (1/4", 1/8" and 1/2").
The Pro 10 body was done with Scotch Masking tape. The one that the full size painters use, cut with a very sharp Xacto.
Now I'm using Duratrax Liquid mask and it's FREEDOM!!!! Total FREEDOM.
Now my bodies will look like they never did before
(of course that after the first crash they'll look like they allways did...)
