Lay 3M flat on table with sticky side up.
Peel failing sticker from board.
Place one tiny bit of edge on and in rolling motion apply to 3M.
Now you won't have one of these. I made it special to get the curves. But cut very carefully around the radius first. Get the edge very close to the sticker edge.
Then do the same with a metal ruler for the straight edges of the sticker.
Will end up looking like this.
Get it lined up perfectly and secure one end with tape both sides.
Lift and carefully peel of backing and cut off.
Press it down in a roll motion but don't put to much if any where you cut the backing. Or you won't be able get hold of it when you do the other end.
Romove tape, lift and expose the backing at the other end. Pull the remaining off and again, roll motion stick down. And you should be done.
Any questions ask. Stupid yellow
