Pitted aluminum rim

[keith4216]

Have a aluminum rim that is pitted on the inside almost to the point of having pin hole leaks. Thinking of useing jb weld or something to fill pits.
Any ideas on this matter? Buying a new rim is last resort.

Say what?

lol What keg did you come out of?

let me simplify. What will adhere to aluminum to fill a pit in the metal?

I used JB weld to fix a thermostat housing on the crossover of an aluminum intake manifold, so I think it will work for you as long as you get the area clean first.
If it is a large area to be fixed like the whole inside of the wheel, I'd be looking for an epoxy based paint/sealant.

Funny Keith but no keg. When I first looked at your post it was all question marks and diamonds. Some issue with my phone decoding the text I guess.

Don't take this wrong, but I can't believe you are asking this question. Buy a new wheel.

If it's to the point of having pin hole leaks, I would just use it as a spare.
Did it have slime or something inside?
JB weld doesn't really bond to all metals. I wouldn't trust it.
Save up for a rim and save you some grief down the road.

Is this pitting on the interior of the wheel or the exterior? What do you think of the structural integrity of the casting at this point? Permatex Right Stuff or JB will seal it right up. You can mount the wheel up in a rotatable fixture or even dismount the tire and install the rim back onto the vehicle and spin the wheel while buffing or sanding the rim. One must be careful to not remove much of the existing rim (something about 16 inch tires on a 15 inch rim). To see what kind of reaction is possible from the Significant Other, fill up the fancy soaking tub in the Master Bath and submerge the wheel/tire assembly in the tub to check for leaks. Be ready to dodge and parry. On a personal note, I'm not much into repairing wheels, replacements are cheap compared to flats, towing, and the occasional trip down through the median at breathtaking velocities. Out in shop, there is a picture of a Model T sitting on a large pane of very thick glass. There are four smallish circles at each point where the tires touch the glass when you are looking up from down below in the photograph. Hand written, by my GrandFather, in the lower corner of the photo, it says; You should have the best tires(rims) and brakes that you can afford, at each of these locations.

Its nothing that a new wheel is needed. Seems fix a flat will eat at aluminum. The rim had a little pitting where the fix a flat found the leak on the lip of the rim where the chrome had peeled and become uneven. Just looking for a filler that can be sanded smooth and then coated with a sealer.
