I've used the 79 Awesome Gloss sealant.
Great Shine. Durability? I dunno... yet.
Tough to control amount applied. Too much, and it becomes *very* difficult to remove.
I've probably used it on 20 cars.
One came back after 2 days (constant rain) with 'haze' on all panels. Actually looked as if I just done a poor job of removing residue, but there was sooo much, that it must have 'appeared' over time. Some kind of a curing issue?
Second car came back with *ugly* trim stains. That classic white residue... No luck with alcohol, solvents... maybe peanut butter next!
Not happy. Not happy at all. Rep coms by Monday morning AM, I'll try to rmember to followup...
BTW, I use their citrus wheel cleaner, XP compound, Super Dress it, and others with good success.
