Ok I have a 79 Super Cab and the bottoms of both super cab sections near the rocker were cut out about 4-5 inches wide from the door to the back of the cab corner, by the PO and never replaced. So now there is surface rust between the body panels. My current plan is to sand blast off the rust as far as I can reach up between the body panels. The vac out the media, clean off the metal with a degreaser. Then apply Eastwoods rust converter, then rust encapsulator, weld thru primer the sharp edges. Then start welding in the patch panel and cover with some kind of putty (thoughts for a brand would be great??) Then cover with and epoxy primer till I do color some time next summer. Any thoughts, questions, suggestions would be great, this is my first run at doing body work

 

sounds like you got it all figured out, i think everything you stated is a fine method. Good luck.

 

I would probably coat all the inside as you mentioned, then take the outside down to bare metal around the patch area. Once welded up and butts welds ground down. I would skim with Evercoat Zgrip, sand, and then epoxy prime. You can add more filler as needed on the epoxy primer. I would then coat with some 2K urethane primer and sand good before finish paint.

 

Thanks for the quick replys! 73FOMO were would be a good place to get the Evercoat Zgrip?

 

What is this Eastwood rust conveter?
Can Do

 

If you go to Eastwoodco.com and look under there rust treatment section there is information about it. But the gist is "Transforms rust into a protective coating that seals and protects".

 

Try tcpglobal.com...or your local professional auto paint supplier. I pick mine up at the local paint store. Zgrip is a good product.

 

Your plan sounds fine. The only caution that I would offer is to MAKE SURE that isyou cut out ALL the rust. It is common for the rust to extend several inches from where it appears.

 

What's the difference between the Black seam sealer(in the tube) from 3m for $9.95 plus shipping and any other Black caulking you can buy from Home Depot for $2.50? I'm sure there is but what they are both silicone based.

 

3M™ Seam Sealer
A one-part, moisture-curing urethane seam sealer that can be painted. No shrinking; no cracking; can be baked at oven temperatures; able to fill large voids.

Don't think regular caulking/silicone can accomplish that.

 

The key is compatible with automotive paints and stability. Not many caulking compounds are stable, meaning that they shrink or crack. This is not somewhere to save $2. Use what your automobile paint supplier recommends.
