By using chemicals other than oxygen in the air to catalyze varnish, the varnish can include desirable anti-oxidants which increase durability. Uses 2-part base and topcoating system, fast drying so all 3 base coats and 2 or more topcoats can be applied done in a day. Manufacturer claims it is flexible enough so that it can go over joints sealed with 5200 and that it is easy to touch up damaged areas. Requires 2 coats of epoxy sealer and several 2-part polyurethane topcoats. Maybe problematic for parts that can not be removed.
Repair processes unclear.
Looks great after 30 months. We have been through several experiments that looked promising for a year or two, but ended up leaving a mess. For this reason, I am inclined to wait a few more years to see how these new systems work out over five years. The alternative, which I am still following until we know more about the durability of these new approaches, is optimizing traditional varnish. Stoppani for final two coats because of superior gloss retention and durability.
