    1. Originally we were worried that the silica sand would be too aggressive, but it turned out fine even on rubber and fiberglass. The pressure washer with abrasive is fairly aggressive, but the water seems to soften the effect of the media, so we weren’t really worried about damaging anything. The walnut shell worked pretty well on CARC coated hoses and glass that we didn’t want to etch, but overall, it wasn’t really effective enough to be worthwhile.
