I would like a couple suggestions on what car care/detailing kits I should get. I am also looking for kits that offer a good range of polishes to remove scratches, oxidation, swirls, etc (PC pads would be great too)...
If you already have a backing plate exceldetail has the cheapest pads at a good quality. Otherwise any kit incl. a BP will save you money.
If you're looking for paint protection look for a kit with microfiber towels.
As far as polishes go, you'll probably just need two MAYBE three. one medium abrasive (like 3M RC, Megs DACP or PB SSR2.5) and one light abrasive. If you run into some heavier stuff then you'll need a heavy abrasive. Two will really start you off nice.
Each site will have a kit/products that will suit your needs quite nicely. It all DEPENDS on what you're looking for.
How many cars? What condition of paint? Are you going for durability or looks? What's your budget?
You'll save money by addressing these questions and searching the forums.
Check out the ones from Sonus, Pinnacle, 4*, Poorboys, or Adams. If they are not listed as "packages" on the site just call the customer service and they'll help you out.
