Well I have tired Wetcoat and Bathe so far, once, but like both right out the gate.

Wetcoat is ridiculously simple to use, beads well and seemed to do everything it said it would (obviously I can't test durability yet). I sealed one wheel uing Meznerna Powerlock and one with Wetcoat. Couldn't see nor feel a difference so at worst, it is on par with what is regarded as one of the better sealants out there, not in terms of durability (it doesn't pretend to) but certainly in terms of looks and slickness.

I then used it on the remaining 3. Its so easy to spray and rinse it into and over all the parts of wheel, brake calipers even plastic arches should you wish - application time reduces dramatically.

Bathe is VERY concentrated, very 'slippery' and cleans well - I think Bathe+ will be even better, especially when combined with wetcoat.

I'll post some more thoughts as a I play with the products more.
