Has anyone else had a problem with their tripoli and white diamond compound bars getting so hard that they no longer transfer to the buffing wheels?
I don't know whether it's the summer heat in my shop or just the age of the bars (3+ years) but when I put them against the buffing wheels they just end up polishing the compound!
If anyone knows how to make these re-usable again and / or prevent this happening again if I end up having to replace them I'd like to hear. I keep them in the original plastic bags they came in so it doesn't seem like they would lose whatever moisture should keep these pliable.
