Re: Wire Wheels questions
I think that blasting a wire wheel would be OK if you do NOT use an abrasive, such as sand or AlO2, as those will remove metal from the rim and spoke. I think that a non-abrasive media such as glass beads or nut shells would be OK.
When I did my wheels, I used several applications of "aircraft paint stripper" to remove many coats of "rattle can" paint and then a 2,000 psi power washer to clean them off.
Since the spokes and rims WILL flex, I primed them with a light coat of epoxy primer, then sprayed a coat of urethane silver metal flake paint. Finally, I applied several light coats of urethane clear coat.
I expected the paint/clear coat to chip and/or peel, especially where two spokes touched each other. I think because I used light, dusting, coats the paint didn't "web" between the spokes and chipping and peeling hasn't happened.
I have not been easy on my wheels (see "wire wheels" thread in this forum), but now, five years later, they still look (almost) as good as they did when I painted them.
