Hi,
If you don't already have them for your PC, definitely consider having a small assortment of backing plates and pads for it.
I'd suggest the new Griots 5" Ventilated Backing Plate for 5.5" Pads, a 3.5" Lake Country Backing Plate for 4" Pads, , and even the smallest 3" LC Backing Plate (actually 2-7/8") for use with 3" Pads.
For Pads, have an assortment of the 5.5 LC Thin Pro, LC 4" and LC or Griots 3". There are of course various other pad choices. Have a few agressivenesses and a good number of each.
As for polishes, I recommend highly, the Wolfgang trio of Polishes, being Wolfgang Uber Compound, Wolfgang Total Swirl Remover, and Wolfgang Finishing Glaze. 8oz of each should be more than enough product on hand to easily do the Vette more than once.
Commonly, the GM paints are a bit on the hard side, and the WG Uber will have a little better cut, and correction with dealing with the slightly deeper sleeks, versus Wolfgang TSR, yet it it finishes down so magnificently like an ultra fine finishing polish, you'll think of stopping right then and there, and going directly to the Wax-Sealant-etc.
The Finishing Glaze is great as the final Polish.
There is not one less than totally stellar product within the entire Wolfgang line. These products cannot be spoken about highly enough all phenominal, the polishes are all world class, and as well all other products with the Wolfgang name on it. The Pad Cleaners, Pad Conditioners, Exterior Trim Sealant, the whole kit and caboodle.
Again, many hundreds of different protectants, but again, and keeping it in the family, products such as Wolfgang Deep Gloss Paint Sealant 3.0, or WG Fuzion would be marvelous picks. After a wash, finish touch ups with something like Pinnacle Crystal Mist Spray Detailer will help keep that deep, dripping wet candy like look.
