I'm giving my Black Chevy Colorado some TLC... Polishing with M210 using primarily a Meguiar's MT300 DA. Also using a Griot's GR3 Rotary and G8 DA for selected areas. I have one side left to finish today then on to the LSP.
Haven't decided on the LSP yet but it will between 303 Graphene Nano Coating, Meguiar's Ultimate Wax, Meguiar's 21 Sealant, Meguiar's 26 Hi Tech Yellow Wax or some combination thereof. I'm leaning towards the 303 and topping it with one of the Meguiar's products to improve the slickness which the 303 lacks. If I opt for a single LSP it will probably be the M21.
We are in the midst of a brutal, weeklong, heat wave with daytime temps near 110 deg F. Installing a though-the-wall air conditioner in my garage several years ago is certainly paying dividends today!
