TIP: Cleaner Mask Edge Lines

Recently I've had some problems with paint lines chipping and tearing when removing the masking tape.
Who knows why?
The paint may be yet another formulation or it could be a change in the weather.

This is one way to help with the problem.
After spraying the second color, run your knife down the tape edge. This cuts a line in the paint and will prevent the paint from tearing and lifting down the masked line.



This is the mask edge after removing the tape.
It'll still need a little cleaning up where the rounded leading edge meets the body tube.
As explained before, I'll "push" the paint (no scraping) back onto itself with a knife blade.
