Yeah, I still love the stuff. I've been refreshing it with ValuGard's Fast Finish for a quickie touchup after a wash, and also with Garry Dean's Beyond Infinity Sealant.
Note that such stuff is, IMO, a completely different approach than 303 and other dressings, which I do use upon occasion.
Oh, and FWIW I do my pre-UTTG cleaning with Griot's Rubber Prep (yeah, on hard plastics too), works *perfectly* IME.
