Waxoyl is another anaerobic urethane/wax based product:

As is Ziebart and the former "System 3" Rusfree is a cheaper version of it.
There are other products on the market, but most are franchised, so the
costs are prohibitive for a shop like mine. I just rustproof repairs, and
the cars done with competitive products have to be taken back to the
original installer or another franchised dealer.

I wish Fiberglass-Evercoat still made System 3. I was an authorized dealer.
