my 92 camaro's underbody is in pretty bad shape. I hada new drivers floor pan installed from inside a few years ago. The pinch welds on both sides are almost gone. The back wheels wells have a hole in them. Ive done alot of fiber glass patching and i just found out yesterday my unibody has a small crack in it up by my k member. Ive had the car repainted and the body looks great, but when u get underneath is looks bad. What should i do? I dont have any pics available right now.

 

The only correct way to do it is to cut the bad out, and weld in new metal. Fiberglass repairs are not going to last when applied to metal. Fiberglass is for fiberglass, metal is for metal.

Also, make careful plans on what you want to do before you decide if you want to do a factory like repair or something custom.

I did a floorpan on my '76 Chevelle, and did it with repair panels meant to duplicate the factory floor, and now I don't have room to run my side exit exhaust the way I want. So I'm going to end up cutting it back out.

Thanks for the reply. Im not sure what i want to do. I originally wanted to do a v8 swap but know im thinking about selling it, but i dont want to sell it to some one with the bad underbody.

 

you can just fix the major issues nowand keep an eye out for a good roller good paint to swap on you parts. they pop up more often than you think

 

you can probably have the crack welded up and if you want to spend the time you can take the fiberglass out weld some patch panels in it then prime it and use an undercoat i personally like the chasis saver you can brush it on and it looks like you spayed it

 

<shrug> it isn't the end of the world. It can be repaired. It can even be made to function better than stock in some cases (like my example with the exhaust).

If you still just want to sell it and your conscience is bothering you, then don't bother with a factory style repair and just have someone patch it in for you.

If patched correctly, you won't even notice the repair unless there's some factory beading missing. I mean essentially the beading could be duplicated as well, but you're talking a lot more fabrication.
