Spray wax is like spray tan, supplemental to keep what you got. It's not meant to do much but get you through to the next real waxing. I use it in between waxes after a wash, but if I were you, I would skip it.
Skip the Makita too, it's too much power. Get a DA polisher, you can't F-UP on a DA, unless you're on crack. Porter Cable 7424XP is the industry standard, but Meguiars makes a decent one too. The DA is best for polishing. You don't have enough arm speed to polish by hand. Waxing can be done by hand, but the DA makes it much easier and keeps your pimp hand on the ready.
Cobra microfiber is expensive. I've found that spending a lot on the towels isn't that good of an idea, because they are gonna get schmeged no matter what you paid for them and I would rather just toss them out. If you buy the
cobra, use them strictly for paint detailing. Go to Costco or walmart or target and buy the cheap microfiber towels specifically for auto detailing, like in the picture, I listed, and use those for the lower half of the car, tires and
rims and interior.
I segment my towels this way.
1. Paint - Spend money here
2. Interior - Costco MicoFiber
3. Rocker Panel - Costco
4.
Rims - Costco
5. Glass - Terry cloth, has more bite.
