Re: paper or plastic?
I mask with paper directly next to paint surfaces and use plastic for large areas, I had some base flake off of plastic once when shooting clear and screwed up the paint.
HOWEVER
Most professional plastic auto masking is NOW corona treated to prevent this from happening. Corona treating alters the static surface charge so the surface attracts rather than repels the paint.
I had paperboard poly coated for years and this is something I had to specify when ordering so printing inks wouldn't fish eye.
