I've gotta fabricate a new section of wheelwell for my "new" quarter section (in the backyard), GM designed these things really well to rust out!! If you're ever on the back passenger side, from the inside of the car, don't chip away the factory caulk going down the joint between the wheelwell and floorpan or you'll get upset really fast!!

So I figured I might as well try beating the panel out; does it matter what kind of wood I use to make the form? Or will bolting a few 2x4's together be enough?

Anyone got any tips? I assume I gotta wear gloves so I don't bash my finger flat...

 

The harder the better, something with a dense grain or no grain is nice also. Something soft like most 2x4’s will just distort as you try to hammer on it.

I like MDF, but oak, maple… will work also

 

Thanks, I never thought about MDF! I'll skip the whole 2x4 thing then, don't want to waste time making something that'll turn into mush on me!
