I do admit to applying a liberal amount to both sides but did check the instruction sheet and it does advise this at least for the first application. I never thought about applying heat especially since its a month since I applied and removed the excess.

In case some are not aware this Professional Select model has particularly thick cowhide so it will have absorbed a lot of the Prooofhide beeswax. I have a new B17 on my Brompton and it is 50% thinner.
