the"Busted knuckle duster"

I have a hard time getting that tape laser straight following the body line. I guess that's where experience comes in. Looks awesome. Keep the updates coming.
If you take a piece of coarse paper like 80 grit on a flat block. You can sand over the edge with the block flat,and it will leave you a good guide line to follow. If its still hard to see spray the car with guide coat first. Works perfect everything. They also make non stretchy straight line tape, but as you probably already know the lines are very seldom actually straight they usually have an arc to them.
