I still have to clean them up..just being lazy and procrastinating since its cold out.
I went to a fabric store, bought a cuple yards of yellow pleather, with some "3M Hi-strength spray Adhesive", ripped off my old rainbows, traced them on the yellow pleather, cut it out, went to my car and stuck them on. I just really felt it out and guessed at what to do, and it wound up being to just spray the adhesive on the door then fit the rainbow on, nad (I used a flat head srew driver) to gently push the extra stuff into the outlining crack of the rainbow. then I usually let it sit and by morning, most of what I thought would be permanent wrinkles were gone. Its a long process, but its worth it.
