Vintage Fuchs, leakage at rim, fix?

[patz]

My 16x7s have an issue. I live at the beach. Getting corrosion points at the bead. Leaks and gradually goes to zero if'n I don't drive it for a week.

I break down the tire and wire brush the issue. Hit it with a hand applied desiccant.

Happens again, different place and wheel within 6 months X4.

Not sure what this dessicant you are applying is, but i would try one of these:
a) get them refinished (anodized)
b) remove the corrosion and seal the bare aluminum (clear coat, wax, etc)

both 7's are leaking? all four? with that sort of loss, a week I would suspect you could see the leaks at the bead with soap?? have you isolated the leak(s)? valve stem maybe?

I might consider just pumping some fix a flat in to them rotate the tire to get the sealer into the leak area.. if the tires are aged the de-beading of an old tire for leaks will likely continue to leak no matter how much you scrub the rims.

buy some new tires and detail the rims then, or buy a can of fix-a-flat or two.

I would try and clean it really good and apply some primer suitable for aluminum. Then paint. If needed some bead sealer could be applied but I don't like relying on it alone.

SC, 6s and 7s. New tires......to quote Joe Bob

FAF BE MESSY. I only use that IF I have an issue on the road. I want a fix until I die.

Patz,
At my day job(running a family owned auto repair shop in Philly)my techs experience this issue daily. We aren't a tire shop per se but sell many tires, what I find works best is to dismount tire, clean rim with either scotch brite pad or 3m roloc disc, depending on the corrosion. After cleaning wipe with rag, apply thin coat of rubberized bead sealer(https://shop.advanceautoparts.com/p/xtra-seal-32-oz.-hd-bead-seal-14-101a/28200234-p?c3ch=PLA&c3nid=28200234-P&c3apidt=23534110797&gclid=EAIaIQobChMI5PCPjdff1QIVxLrACh1-Cw2cEAQYASABEgJbgfD_BwE&gclsrc=aw.ds), re-mount tire, and the most important step, Fill tire with DRY AIR. Follow these steps and you should be in good shape.

Also, don't ever use fix-a-flat, unless you are stranded hundreds of miles from a shop.

I have an auger, a plug and an 12V air pump for my on the road schizzle.

I will use a FAF when I am dying of thirst.

I just wanna fix my schnitzel at home.

Yeah, if there is pitting you are going to need some sealer. Shouldn't need paint but it might keep further corrosion at bay longer.

Bead sealer like the other said. It's pretty good stuff, will hold air vs rusty, beat up rims.
