Sealant for leaky alumin(i)um wheel rim?

I have one tire that always loses pressure faster than the others --
even after a tire replacement, so I am suspecting that the alloy wheel
itself is leaking -- ether through porosity of the alloy itself (not
unknown, I understand) or through corrosion or other damage to the rim.
I have read that sealants are available to deal with this problem, but I
have been unable to locate any -- except a huge drum of the stuff for
$2000+. Can anybody suggest a suitable product -- preferably by brand name?

Squirt some soapy water all around the rim (both sides) and the valve stem and look for bubbles. If you see bubbles around the valve stem replace it. If there are bubbles at some spot(s) along the rubber/rim interface, 1) u nseat the bead at the leaky area(s), 2)thoroughly dry the rubber and the ri m if they are still wet from the soapy water, 3)lay a thin layer of silicon e seal on the rubber, 4)reseat the tire bead on the rim with a big dose of compressed air. Worked for me after the tire man did two unsuccessful trie s using his standard thin rim sealant. Good luck.

If you can't put some fast air in the tire, squirt some either in there and throw a match at it, be prepared to run FAST!

that is all crap, you take the tire off the rim, then use a powered wire brush on the seating area, once the rim is clean of oxidized alum, then put tire lube and reasemble. Have not had one rim that wasnt compleatly shot leak again. KB
