I got some Menzerna Powerlock from CYC last week, and have used it on every car I've done since (paretns, GF, neighbours etc) and I must say, it's one of the nicest LSP's I've ever used.
It speads like a liquid wax, you can leave it as long as you want and it buffs off with absolute ease, it sheets like a sealant, beads like a wax and has a nice 'glow' to it, unlike most sealants, which can look a bit sterile and plasticky on some colours.
Few pics today on my Golf:
(excuse the quality, they are iPhone pics!!)

It's massive in the States and I can see why now!!
MASSIVELY overlooked on here - you're missing out!!
Anyone else using it?
