The moisture cured epoxies are quite a bit more brittle which some may find reassuring as a sign of strength.
Personally I want an epoxy that has some flex and give making it less susceptible to cracking from rock strikes and letting moisture in.
I tried the chassi saver once. Some stuck some stripped off in sheets.
I'll stick with a quality epoxy that was used on the pebble beach concours winner this year. Southern Polyurethanes inc.
More protection less cost. Was a no brainer for me.
