Anyone heard of JB Weld on knuckle ball pitting?

I did a reasonable search on the subject and I can't seem to find any info.
I read a while back it was possible to fill the pitting on the outside of a solid axle knuckle ball to smooth it out.
If there is a write up or link to this procedure would you kindly pass it along?
thanks

Clean the surface, apply the filler, smooth it out and let cure. Sand smooth and you are done. You could probably find a link to auto body filler application, same basic idea.

I actually am in the process of doing it. The JB Weld doesn't seem to be setting up. It is still very tacky and it has been more than 6 hours. It is wet and humid here and that may have something to do with it. I will see what happens in the morning.
Thanks for the response!

Sounds like you didn't use enough hardener or your hardener went bad.

I went out in the freezing rain and scraped off what I applied earlier.
The JB Weld I was using is at least 10 years old and wasn't curing. I figure the hardener is shot and it would be better to start from new.
I will post up a few pics of the process in a few days.

A little extreme?

I've done the JB after cleaning. Worked good.

JB takes some time to cure, usually overnight. A heat lamp to keep it warm does help. It has to be warm to cure.

24hrs later and two heat lamps 3" away and the JB Weld is fully cured. Amazingly it acts just like bondo (which I am far too familiar with.) lol
I took the JB W down very close to the edge and feathered it out. It is NOT a cosmetic fix but rather a functioning fix. I also put a little on the inside outside of the inner axle seal housing.
I cant see any reason why this procedure wont work to help maintain fit and seal.
Sorry about the big pics..
