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?

They are usually held on by little clips you can buy from auto parts store. I would glue it with some kind of adhesive that is waterproof and stays soft like a sika product or similar. Those coming off are a known issue for Subaru
Is this wheel well trim or is this rear door seal trim that’s hanging out? If its door seal, it has small plastics clips that clip into the door, you can buy them cheap on aliexpress, or expensive at the dealership
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.
I’d probably cut it off.
Look for different types of automotive push clips, construction adhesive like loctite 3PL or similar.
See what the manufacturer uses and do that.
3M DP420, assuming you never -ever- want it to come off again.
I would have sworn you were trolling with “dp 420”
One would think, but you definitely want to keep “DP 420” and DP420 farrr away from each other.
