patch panel rust prefention
with the extreem amount of rust in my cab i will be cutting out the rotted areas and welding in patch panels. on the less complex areas i will be useing flat sheet metal, on the more complex areas il be useing patch panels from lmc (door jams, drip rails, and cab corners,) just wondering how i can keep the back of the panels i cant get to from rusting. ive thought about just shooting it with some ratle can primer and welding it in but the weld will burn off the primer and im back to the same problem. should i even worry about it or am i overlooking a simple solution?

Dont weld. Use panel adhesive. Prep the panel and tape off where the adhesive will be going then paint the rest of the back of the panel. Then when the paint has dried and the tape is removed apply the adhesive on the bare spot and put it in place. then there is no chance for the rot to come back.

i know exactly what your talking about, but how would i use that on the cab corners and roof panels where it would otherwise have to be butt welded so it wouldnt overlap. i will deffinatly will do that with the floor pans!!

Drill holes on the opposite side of the weld and then go crazy with the rattle can...depending if anything is in the way you should cover it... I personaly wouldnt glue anything together... just kinda seems like it goes along the lines of the previous owners that rivet and caulk floors in on trucks...

Panel adheasive is definately NOT calk. And as 77F250 stated, get a flanging tool. I used one to "glue" the gas tank door in flush

weld thru primer, just be sure it is totally DRY before welding. Next, shoot Eastwood heavy duty anti rust inside the cavity if it is accessible.

If welding is so much preferred over the many, many professional panel adhesives on the market these days, why is it EVERY professional shop I know now uses adhesives to glue in the non-structural patches these days? I have welded many patch panels in, and I have also glued some. With that said, if you prep correctly, I would take glue in over welding any day. You are way less prone to warping your panels by gluing them in, and the glue squeezes out at all the seams and does not allow for the corrosion to start as it does with welds. Also, since the floors are considered structural, you should weld those in instead of gluing them. Any time its possible, I choose adhesive over welding any day.

Ahhhh, see....most of my stuff isnt used for sunday trailer park recreation. I cant honestly see why you would want to go after a new patch panel with your size twelve, but to each his own. I seriously doubt you would be able to seperate it any ways. Just out of curiosity, how many panels have you welded versus glued in?
on a 69 nova... floors quarters firewall round windows.. trunk pan...
Glued:None dont trust it... I dobt It will last as long as welding..

Well a year later the truck came back need ing the same bed side replaced do to similar damage. Tell you what. it normally takes about 30 min to a hour to remove a welded on bed side. It took almost 2 hours to remove the glued on side. That was enough proof for me and i have NEVER seen the glue fail
