Fender well repair.

Looking for any advice or recommendations on repair material to fix a hole or two on original front inner fender wells for 1970. There are a lot of products by 3M and Fusor and I am sure others. There has been some repair documented on here but only info is 3M plastic bumper repair when there are numerous part #s. Looking to repair around where cage nut goes and fastens to fender and a couple other small holes. The material I would think would have to be a little flexible and not too rigid and be able to bond to the plastic and be sanded. Any info from your experience is appreciated.

I go there all the time and today I went and Bob wasn't there and I have to wonder about his knowledge since he's a little long in the tooth. The other guy really didn't give me a good feeling he knew his stuff, he kept saying something about knowing what type of plastic it is and oils and stuff. I need someone in the trenches that knows exactly what to use. I will figure it out, just looking for prior experiences.
Thx P

I believe that the fender wells are polypropylene.

That would be the place to start.

I want to repair my inner wells as well, they have some gouged out holes where the tinnerman nuts go. I came across this site: https://www.polyvance.com/vista.php I have the heat gun & nozzle accessories, but have not purchased the polypropylene from them, so I don't know how well it works, but will try it this winter.

Interesting, This is the kind of stuff I like to learn about. Thanks for your input. It looks a bit pricey for all the stuff is the poly just melted in? I have to read some more.

As I understand it, you heat the fresh polypropylene "stick" until its soft enough to work it into the hole or crack. Then sand it down. I haven't tried it, but in working with other plastic items I've found that warming the mating area is helpful, but not too much as the original area may become deformed.
