I am working on a 90 hf and the rockers need replaced. The only place to get a new one is Honda. Not a big deal! The question is when welding the new one in can I butt weld it? A local body shop said that I would have to cut a piece of the old rocker and weld it in behind the new one. Because of it being a unibody car! If somebody knows it would really help.

Thanks for any info

 

its not a good idea to butt weld it, if you want to use a used peice, use an over sized piece and trim out the rust on it on the old one, knock the origional one down a bit and weld the new one over the top of it, using a weld through primer

 

So I do want to reinforce it when welding the new one in. I just wanted to make sure that was the way to do it. He said that he cuts out the old one and then takes a good strip from the old one drills holes in both panels tacks them then welds in place. What could I use for keeping the rust away between the two panels? I have to get new ones every CRX I find has rusted rockers! Also Would I have do the same for patch panels for the quarters?

 

use zinc rich primer in between the two where you will not be welding and weld through primer where you will be welding
