I would never recommend a novice use a rotary, but as you know I am beyond novice. I was just letting Andy know that Adam's products can be used with a rotary with great results.
A paint cleaner won't do more than SHR, most paint cleaners are far less abrasive. If SHR by hand hasn't taken care of it a machine is about all you've got left.
I don't wash my APW applicator, the vehicle is as clean as it's going to get by the time I'm ready to wax and the applicator is already loaded when I go to use it again. I also don't like washing away good wax.
This one was really involved and keep in mind I use a rotary. I started out with SWH on a nanofoamedwool pad, then SWH on a orange pad, FMP on green LC pad, final was Menzerna PO85rd on LC blue pad for the jeweling, finished up with 2 coats of APW.
