The rubber trim in the wheel well of my sister's car separated from the steel frame. What's the best way to reattach it?
Obviously I'll clean the steel and rubber with soap and water, and probably use some kind of adhesive. I know it needs to be weather proof and vibration proof. I was thinking construction adhesive, but I think that would fail the vibration test. Then I thought epoxy, but standard epoxy would probably have the same issue. What about steel reinforced epoxy?
Any other suggestions? Should I use an abbrasive like steel wool?
What kind of car is it? Do you have any better pictures of inside the wheel well, or know how it's supposed to be attached? You might be able to take out some of the trim clips for the fender liner and pull the fender off and find that you can just slip it back into a groove or something. If you need to glue it, epoxy would work fine, or a silicone would work well too.
I'd recommend silicone glue also, but I wouldn't use epoxy, that'll harden completely solid and won't long stay attached with road vibrations and all.
OP, like the person above said, check for any clips or grooves or whatever first. If you absolutely have to glue it back on, make sure all the surfaces are clean first, and make sure to tape it up in place temporarily while the glue dries. I'd give it a whole 24 hours drying time with silicone glue.
