Welding patch on rocker panels

[AbsorbantNut]

OK, so I have a rear part of the rocker rusted out and the front half is good. I Just want to weld in a patch panel after I cut out the rust. I dont want to replace the whole rocker, only the rusted part.

The only thing IM worried about is the inside of hte panel. When I weld it will burn off the paint on the inside of the rocker. And arent their rocker drains, AKA water flows inside of the panel?

So my question is how do I weld it and some how seal up the rear of the panel and rust proof it? Thanks ahead of time guys.

In general, where there's a little bit of rust on a rocker, there's more you can't see. Start cutting until you get to reasonably solid metal. Use converter on the rest. Prime with weld-through primer. Cut the patch to fit and weld it in.

It's usually easiest to buy a replacement rocker panel. However, it's often easier to cut it so you only replace what you have to.

Hahaha, tell me about it. I know how bad its going to be, and the exact size that needs to be cut out. The guy before me welded a patch in as a favor since I couldnt weld at the time. It was only a few tacks and didnt really fit right.

So my plan is to cut out that patch, clean it up and weld a new patch. I have 2 2 foot sections of rocker panel to patch it up with, which is more than enough that was chopped from a parts car.

Would you mind specifying what you mean by converter? They have weld through primer?! Thats sweet. So I guess just cover all exposed metal with the primer, then weld it on, and hope that it never rusts from the back side?

And then chassis wax. Don't be afraid to drill a few access holes to spray it. Also, you can get good coverage with paint after the fact with a few strategic holes. As you noticed, the rocker isn't sealed, so this isn't a big deal.

OK, thanks!

Rust converter and weld-thru primer is available from a number of vendors. Eastwood.com is one I often use.

I also need to do this. Fucking rust.
