its pretty easy i think.... spray bottle with a little soap. spray the light down lightly. hold the vinyl up and heat it. then apply it in the middle or the base of a convex and start heating and stretching from there then clean the edges with a razor blade.
its alot harder on the P5 tails, you have to start in the middle, then heat and stretch towards the outsides. Its going to take a while, alot of heating and stretching in different directions is involved
