How do I cover a hole in inner wheel well?

I was trying to clean up some protruding metal but went to far . There’s a rubberish/ tar material already there from factory. Does anyone now what it’s called and where I can buy it?

 

Maybe a can of flex seal? They did make a boat out of a screen door..

 

You were cutting the pinch weld off, weren't you? Then I take it that's metal?
You have two options:
1: weld a patch panel in and finish with paint, etc.

2: use automotive panel adhesive to attach a panel in place. I'm not talking about Goop, or caulking (although it comes in a caulking tube):

$55 3M Panel Bonding Adhesive 08115, OEM Recommended Two-Part Epoxy, 200 mL Cartridge, Bonds Metal & Composites for Auto Body Panel Repair (1 Cartridge)

This is the same stuff that auto manufacturers are using nowadays instead of spot welding some panels in place. It's more user friendly if you don't have access to a welder, but it provides a strong bond that is water proof and corrosion resistant.


While you're at it, I'd pick up some seam sealer and hit the area that you cut. That pinch weld was waterproof until you cut it and if you left even a pin hole for water to get in, it will find it.

Good luck

 

Black tire sealant and sand. Cheap and effective and doesnt look too bad.

 

lol my co-worker said the same thing

 

i was cutting that area. BIG MISTAKE. it is metal.
Thanks, thats what I'm going to end up doing.
i have no time right now so i used jb weld since its raining. Temporary fix.
