porus wheels

[dsmith]

I have tried to search for a post that I have saw a while ago but have been unable to find it - perhaps someone either knows where or what to search for, or knows the answer to my question.

I am getting ready to put new tires on my ERA #64. Am currently having a leaking problem with the older BFG's that are on it. Have had them off the rims and remounted and new valve stems installed, but still have a slow leak, especially in my front left.

Bob In Ct suggested the casting for the wheel may be porus - allowing air to leak. While I have the wheels off for new tires, I figure it would be a good time to seal them up as a precautionary measure.

I remember reading something about this, but as I said before, I couldn't turn it up with a search.

Anybody remember what was used to seal the wheels???

thanks

ps
Haven't made my mind up about tire choice - Yoko or Dunlop. Thanks to everyone that responded to my tire choice question. The Avon's that Fred Z recomended will probably be to expensive to ship from Calli to Conn, so I guess it is down to an American tire or a Jap tire. I have seen the Dunlops and wish they had a more aggresive looking tread pattern, haven't seen the yokos..... decissions - decissions...

I think he mentioned something about using epoxy paint.

I had an area about the size of a 50¢ piece that was porous and leaking pretty bad. PSE fixed it by using an air chisle/hammer to peen the area over. Worked like a champ. Phil says they do that all the time.

There's a product called Microseal that is made to seal tiny holes in aluminum and other cast products. We've used it at work, but I've never tried it on wheels.

You might try that - it's a paint on application.

You could also consider powder coating the interior of the wheels.

I believe the peening method Frank mentioned is commonly used in the wheel industry.
