the one that I've found lasted the longest is fK1000P, I got more than a few months out of that.
I prefer to use definitive wax Rotundas, this lasts a month or so.
I did tend to use ceramic sealants, but TBH, what I've found is nothing really lasts depending on the brake size/wheel config... the bigger the discs/caliper and heat, the less it lasts... especially if the wheels 'just' fit round the big brakes! lol
but, when all is said and done FK1000P is a decent high temp wax, can be used on wheels and bodywork, lasts for ages and is very well priced for the massive tin you get...
