Bought my wife a new ES350 late last winter and luckily it has stayed in the garage in the worst of the weather. It has seen very little salt, gravel, etc.
It has had one treatment of Sealant, Glaze and Buttery Wax; I have recently started using the H20 GG.
I would like to get another coat of protection on it before winter.
Is it best to strip it all the way down or can i apply Sealant and/or Glaze and/or Wax on top of what layers still exist?
Will the sealant permeate the wax if i don't (and is wasted effort)?
Thanks
