I ran over a piece of bent scrap bar in my yard and it swung up inside my rear fender and pushed the fender extension about a 1/4" off the main body.

I can see the screws through the gap that hold the parts together. I don't seem to have bent any metal... just pushed the extension off a bit.

Can I repair this situation myself... If so what should I do?

:ts:

....perhaps if you could show the damage with photos?

hi are you talking about the fender flare.
if thats the case you can have it repainted, or just take it to a vinyl shop and have it covered. they use the clear protection film for the front bumper, hood, mirrors, and side fender flares, or i have seen a ferrerri the whole car was done.

they also have trucks done now as ad's, fo there business's.so th whole truck, car , whatever get's wraped. it what it is really called.
hope it help's,
