It's a vibratory tumbling process. Will not say much more than that as we've worked very hard to perfect this process, chemicals and media. It's the best for restoring aluminum, and our process meets all NCRS standards too.
Not dull like sand blasting or glass beading would leave it, leaves a nice satin shine just like when the casting was new. No dust issues or finger prints when touching it. The best part is the care. If you spill gas or anything on it, you just take a can of brake clean and a paper towel and wipe it down. Don't believe me, read the feedback on our web site, www.z28camaro.com
. We do most of the high end resto shops aluminum work and repair nationwide. A lot of high profile people on our site.
