I hear ya. I'm just getting back into pan cars with my BMI Copperhead 12. Thanks for the head's up on the CRC wheels. I'm planning on just using shoe goo whenever I do start mounting. Even back when I ran 1/10 oval I never tried to get absolutely all the old foam off the wheel, just put the wheel on the truer until I got off everything I could, then shoe goo, new donut, and true it back up. Always worked fine as long as about 1/4" from each wheel edge was totally clean, which emery paper on the truer will take care of.

Probably going to be at least the end of the year before I have enough wheels sitting around to even bother though.
