Ok, I keep getting more and more PM's about what someone needs to buy to get started. So, here's a list. It's not the end all be all list, but it's a good start. With the stuff listed here, you can make the paint look very nice if you know what you are doing.
#1 A real buffer. A Porter Cable 7424XP is what I use, but any GOOD DA is ok to start out with. With a DA you don't have to worry about hurting your paint like with a rotary. THEY DO NOT SELL REAL BUFFERS AT VATOZONE OR WALMART, PERIOD
#2 A backing plate for the DA. This allows you to use any of the standard pads. Probably a 5.5" is the best choice.
#3 Pads- I use Lake Country Hydrotech pads since they are more versatile and allow you to waste less product because they hold the product at the surface and do not let it soak in as much as other pads.
I use Cyan Pads for heavier cutting (like with M105, Ultimate Compound, Swirl-X)
I use Tangerine Pads for light cutting (for M205)
I use Crimson Pads for applying pure/non-abrasive polish, sealant, or liquid wax (which I don't really use)
If you don't want to use the Hydrotech pads you can use. . . . .
Yellow pads for M105, etc. (cutting)
Orange pads for M205, etc. (light cutting)
and Blue or Black finishing pads for application of non-abrasives, sealants, waxes.
#4 MF towels. There are many different kinds of them. You want to pay attention to what kind you use for which job.
Don't use a drying towel to remove wax, don't use a window towel to dry the car.
I keep the MF towels I use for product removal completely separate from all my
other towels, always. I don't want to risk using a MF that I polish my wheels with
on my paint, even if I wash it.
Get good MF towels that are purpose specific. Different towels have different
nap and different uses.
#5 Products- You can't go wrong with M105 and M205 for heavy and light polishing. These are all I use and have no reason to switch up to anything else.
BlackFire Wet Diamond is the shit when it comes to a sealant, period. Great on dark cars, too. Zanio products are also good sealants. I'll probably start buying their full line in the future when I run out of all the crap I have now, lol
Wax is completely up to the user, too many options out there to pick a favorite. For the price I like Natty's Blue or Natty's red. Not that it's the best wax by any means, but for the price, it's pretty damn good.
Spray Detailer- You need this, not just for a quick detail, but to go over your car to make sure all of the excess of the products you are using are removed. Also used for Claying the car.
If I'm inside I like either Meguiar's Ultimate Quick Detailer or Optimum Instant Detailer and Gloss enhancer. If I'm at a car show in the sun I only use Meguiar's Ultimate Quick Wax.
#6 Tape- Low tack Delicate Blue Painter's Tape is a life and time saver. Mask off the car before starting, much easier
#7 Clay Bar- Chemical Guys clay is good. Mother's is good for over the counter stuff. Meguiar's is also good.
#8 Wash- I use Chemical Guys Maxi-Suds for washing and for my foam gun.
I use Chemical Guys Citrus wash for stripping off wax for a full detail.
On my Other cars I use Meguiar's Gold Class Car wash
#9 Dressing- For a good all in one dressing that will work on tires and engine I love Meguiar's Hyper Dressing. Great Value since you dilute it down with water. And yes, it's water based, not silicone and it's much better for your rubber and your paint
If I've missed anything, ask away. This is a simple list, and there are a lot of options out there, but this is easy to find and a good balance between quality and cost efficiency.
