I have some rust holes in my rockers but dont want replace whole rocker can I just grind off all rust and fill with bondo? I am new to body work but im trying to save a buck

 

Make skins and glue em over it. Cover it all with spay bed coat Bottom 8 inches or so. You can also get it sprayed, just like the bed, real tough stuff. Filling it in will just make it rust faster. You can buy a skin and cut it to fit over the old one. Paint it on the inside before attaching it to the old. Let it dry for a couple of days to cure. Even real tree it for effects.

 

What abot that expandable foam stuff?

 

The rockers on these trucks seem to rust from the inside out, hope yours wont turn out like mine did ground out all rust til I got to solid sheet metal didn't stop til about a half inch above the door line, I ended up reshaping the whole thing with expanding foam wrapped it with fiberglass and gave it literally a quarter inch thick coat of herculiner on the bottom and in side then went about 6-8 inches up around the whole truck giving it a green/herculiner 2-tone, give the bottom a good push with your thumb if it goes through you're screwed, best of luck

 

How does that foam hold up and what exactly is it called

 

I went to the hardware store and picked up a couple of cans of Great Stuff and as far as I know it's still there but like I said that was just to get my rough shape back, the main structure is now fiberglass

 

Ok does it seem like itl hold I need sonething thatl hold for 2/3 years and il be happy

 

Any pix

 

Not trying to be mean, but wouldnt it be better with the work and cost of doing the above procedures to just replace the rocker? The only reason I say this is at least you know that it will last, not just hoping for a few years. It would be steel, and no worry of damaging it when you bump it with something. Because you really dont know how long a patch like that will hold. Hell, duct tape might do a decent enough job.

I understand if you dont have the time or tools to replace the rocker. Either way its still a decent amount of work to do.

 

I might just have a shop do the rocker and do all the paint myself anyone wana guess a cost for me?
