I recently sanded down my fourtrax and painted w/ krylon 'fusion' gloss black paint. I then put 2 layers of clear. Now, i'm thinking of putting the 3m clear bra stuff on it to keep from scratching the new paint. Has anyone done this? only place i know who sells it locally is walmart. They want $15 for 2 10"x16" sheets. Anyone know of a cheaper place to get it?
