Skin Corrosion Repair Advice


New trailer owner here...."65 Safari with 3 spots similar to this. Can I cut this out and rivet a larger patch over the void. Obviously want to fix it right once and for all. Thanks everyone!

Why cut it out - just cover it up.
I would run the patch all the way to the wheel well - one less 'edge' - would look less like a patch.

Agreed. Don't cut out the old section, just make a large patch that blends in as best as you can.

Jj kit, you will need to fix the corrosion cause 1st then repair or cover up.

I have this on my 54 Cruiser. Mine is on the belly pan panel which will be replaced anyway with my shell off resto.

Ensure it is corrosion or wear. Mine looks more like wear due to failure of the bond of the panels and the floor in the area. And some corrosion.

Either way, the aluminum is touching the outrigger which is where the corrosion is occurring and the wear due to movement.

Again, resolve the issue before covering it up. Also, check the structure between the floor and exterior panel.

Thanks. I read somewhere on here that corrosion is like cancer and must be dealt with or else if simply patched over it will continue to corrode. Obviously it would be simple to cut out a patch and rivet it on but I do not want further problems. Should the rib be grinded back to prevent further degradation of the skin?

In the Navy, to preserve and protect, we used a Zinc Chromate primer on my last Spruance Class Destroyer. Everything from the main deck up is (was) aluminum, and that as a basecoat over bare Al prevented all kinds of corrosion from the elements. There are other primers and coatings that you could use, but the Zinc Chromate works best over the long haul. Any place that sells marine coatings should be able to get it for you. As far as a patch or repair, that will be your aesthetic choice. Hope it works out like you want it to.

Same thing happened to our 63 Safari, caused by a cracked outrigger, it had to be straightened, welded & primed with Z-chromate.

Galvanic corrosion
