Did a decent PGP test on the weekend - 450 miles through the desert to Northern AZ, with 450 miles of dust on the car, and 450 miles of bug guts baked on at 109 degrees!
Did a basic two bucket wash with a real wool mitt - usual hose down to start, then wash panel by panel with lots of suds, then rinse, then nozzle-less water sheeting.
Dried the little remaining water with a MF towel.
No speed detailer or additional PGP - this is a one coat application to date.
Noted that the PGP beads really well as expected, the dust came off during initial rinse, and the bug guts came of very easily without leaving any residue using the mitt, and without appearing to have effected the finish.
Also noted that cleaning the car added no new swirls - which is HUGE! - so

to PGP on protecting the finish.
Results from 20 mins of wash and dry:
Still loving the Ultima result!
Of course, now I'm back in CA I need to wash the car all over again!
