You must have a good supply of it then lol.Looking good, I like the curve.
Frisk (or frisket) film is used a lot in custom paintwork and airbrushing but I haven't seen it used much in modelling. I sometimes use it for masking around stickers or graphics on vehicles that we don't want to remove and refit. If I spray the colour lightly up to it then remove before clearcoating the edge is almost invisible.
I like it for many reasons. Its low tac, easy to cut and can be pulled off and stuck down a few times. Useful for multi-colour work.
It can be a pain if it stretches, but it's stretch does make it handy for doing curves..... I really should use it more.
