Don't you find using a paint cleanser stage TOTALLY transforms the wax experience later?
I loath using a wax unless I've either used clay or a paint cleanser (eg. SRP or Autofinesse Tripple). The surface would just feel grabby preventing smooth application and buffing of the wax.
But after a paint cleanse, waxing just feels SOOOO good, with the wax spreading thinly and effortlessly over the paint and buffing off with the slightest of pressure.
Very envious of you having the time to do this.
Was just a normal wash and a drying aid LSP for me this week.
