Humm... a short piece of ABS water pipe cut down the length of it and unrolled with the heat gun and pressed flat would make a good backing for it... but the paint needs to be removed.... both surfaces scratched up good with 80 grit sand paper and then glued with plumbers cement for ABS should make it very permanent.. then you need to match the paint which is probably the hardest task of all ! LOL
.... My Dad spent a good 30 to 45 years as a body and fender repairman
had his own shop and all that, he taught me alot about repair work, but he was color blind and could match paint better than anyone I've ever met....
I never could match paint... the harder I tried the worse it got !
LOL....
My how times change... used to be metal fenders now it's ABS fairings !
HAHAHAHAH
