Welcome
I found when I was first getting into serious detailing I found that I wanted to start getting the car clean and keeping the car clean. Naturally, I tried several shampoos, wash mitts, microfiber towels, clay bars, various brushes, and of course the dual bucket method with grit guards. I figured that I would start cleaning the car the right way, and after I had learned how to clean the car the right way, and keep it clean, I would move on to learning how to polish the paint to get it swirl free. This way, after you achieve a swirl-free finish (Which is acquirable from your PC7424), you will be able to keep that swirl free finish by properly maintaining it with regular washes that don't inflict more damage on your paint.
I would recommend a sheepskin wash mitt, either the regular one or the 2-in-1 sheepskin wash mitt you can find at Autogeek.
For washing, I love Pinnacle Bodywork Shampoo. That may be a bit expensive for you since you're just starting in the game, so Duragloss #901 car wash would be a very good choice for you.
Also, high quality microfibers are very important to detailing. They can make or break your detail. Its the worst feeling in the world to completely buff out a car, and then inflict more scratches while wiping it down with IPA or Top Inspection, or even the LSPs. I PERSONALLY don't use Cobra's microfiber products, I use another manufacturers, but Cobra microfibers are much better than what you can get at your local WalMart.
A good clay bar to decontaminate your car with is the Clay Magic clay kit. I like mothers too, but some find it too soft.
For waxes from AG, I'd suggest DP Poli Coat paint sealant as your sealant ( a sealant is longer lasting than a wax, and is made of polymers as opposed to carnauba). For a wax, I'd suggest DP Max Wax or Pinnacle Signature Series II. I love SSII and DP Poli Coat.
Hope this helps :xyxthumbs:
By the way, I'm from Winder, GA, not too far from you!
