The Stovebolt Site Forums The Shop Area Paint and Body Shop Need some advise on patching cab corners

Please look at the right side rust holes
Right Cab Corner

Left Cab Corner

I dont want to cut the whole piece for the replacement cab corners they see but the curvy area is making me nervous to cut some piece and patch up.

Any ideas you guys have

We cut out what we needed from the outer cab corner replacement panels.

Once you clear away the paint/primer, you will probably find that the rust is more extensive.

The replacement paels do not have the original weep holes.

oh know actually I had cleaned paint rust and everything found only those rusts and holes, this cab is recently primed fresh. Inside the cab I have rust encapsulator coated. I tried to know around those rust spots and rest of the metal is strong. My theory was since I have rust encapsulator is painted inside and outside is all cleaned out, guess is it should not rust more and so can I patch with some filler material and not worry at all. I am trying to avoid cutting two major cab corners.

why not cut yhe rust out and fix the rust correctly so you dont heve filler covering the rust holes? i just got done replacing my cab corners it is easy. and you will have less filler and a better job. and the rust wont come back in the future

The best is to cut out the bad and put in the new. If you must here is what I have done in the past. Sand the primer but don't sand it to metal. It is good if the primer is 2 part epoxy. Put some nylon screen on the back side and hold it in place with masking tape on the front. Mix up some JB Weld and apply it to the back side and push the masking tape in from the front to dimple it down some. Let it harden, lightly sand and put another coat of JB Weld. After it is hardened use some bondo like material on the front and sand smooth. Prime with 2 part epoxy and paint. This is not a life time patch but if you removed all of the rust in the first place it will last for years. Again the best way to deal with it is a patch panel.

Thanks neilroy, lot of people might like the idea of doing this kind of patch. but an option to fix it

If that is really all there is, a competent welder could weld those holes up. You would have to clean everything down to the good metal. Then come time with a file and you are done.

Hey 53chev......do you have to remove the bed in order to replace those cab corners or can you get to it with the bed on?

Spot

You will at least have to slide the bed back a foot or so or jack the front up might work better. It really depends on what shape the old ones are in and how much you have to remove.

I looked at my cab today, as this is a future project. It looks to me like you could jack up the back of the cab and remove the splash aprons then you could do it. Like Neil said though it depends on how much you need to replace.

Nobody can weld up rust holes.
