    This is when I was using glass bead media at 100 psi to blast with and the beads would embed themselves into the metal then pop out when heated. I changed to coal slag and the problem went away.

    I have had this on some of the rims I have down. On mine it was because of the blasting media getting wedged in between the two metals. Also on chrome rims that were blasted to remove the chrome, but could not get all of the chrome off in between the two pieces of metal.

    I guy near me, John from Color Life, who did stuff for Indian Larry, is sick now with Diabetes, but just recently he was telling me that he lets the guy at TDO sandblast for him, because TDO used a red ceramic or powdered brick that absorbs oil. He called it Reno or something, that is what it sounded like. Sometimes I do a combination of aluminum and iron, and if I give it to anyone else, he won't guarantee the powder.

    Sincerely,

    aluminum and IRON???
    isn't that THERMITE???
    do you mix it yourself or do you buy it in bulk?
    I know it's been the better part of a year since you posted that, but the aluminum and iron thing really caught my attention.

    I am not sure what went wrong here. I had 3 items, all looked great when I had them cured in reflective chrome, this happen when I applied the clear . I did apply the clear with the item warm. The other two items turned out great. Thanks, Russ
