Auto Detailing 101
Top Gear has it down pretty good, but I would agree to disagree on a few things, lol. I exclusively use
Chemical Guys/SmartWax products.
Chemical Guys is a higher quality (and yes more expensive, but lasts longer because you don't have to use as much) than the SmartWax products.
I gave up my shammy about 4 years ago when I learned that, yes; it picks up water well and is lint free, but it also removes polish and wax. A microfiber towel of the same size blows a shammy "out of the water" so to speak. It's easier to use, picks up more water, rings out better, washes easier and lasts longer; and it doesn't get all stiff like beef jerky when it's dry, lol.
One thing I didn't see Top Gear talk about, and this is something I learned. What most people don't realize is with the later model cars, the paint, just like a persons skin, is "porous". So when I wash, clay, polish and wax your car, it's like giving it a facial treatment. Failure to keep your skin clean will cause your pores to become clogged, your skin will turn grey and begin to breakout; it will become rough and craggy to the touch, etc; well the same thing happens to your car if your don't keep it clean.
I start out by rinsing off the dirt, then scrubbing the tires and cleaning the
rims with soapy water, rinsing them off afterwards. Next I rinse the car off and then section by section, wash it. The secret here to minimizing surface scratches (the swirly marks you see in a cars paint when you look at it from a certain angle), is to use a soap that removes the dirt from the surface of the paint and holds it, so that while I'm washing the car using a microfiber mitt, no scratches will occur. Once again I rinse the car off.
At a certain point, washing and even waxing your car is not enough to maintain, or obtain a glossy, smooth, shine on the surface. When contaminants such as bird droppings, brake dust and environmental pollutants settle and stay on your car's surface, they become stuck in the top layer of the paint. You can wash and wax all you want, but soap, water and wax won't remove them; the only safe way to remove all of these contaminants is with a clay bar treatment. Using a clay bar on a car will make the surface smooth and ready for polishing and waxing.
While the car is still wet I begin the "claying" process. I prefer a pre-made clay bar, which is literally a piece of clay attached to a "sponge" that I run over the car (including the windows) to remove the afore mentioned contaminants that dull and damage your cars paint job. This is the equivalent of having a mask applied during a facial to pull all the impurities from your skin. When I was doing a white car after washing it, even though it appeared clean, as I was claying it, the remaining liquid residue that was coming off was brownish-yellow in color. After the claying process I rinse the car off again and then dry it with a microfiber towel. At this point I also open the trunk, hood, doors and gas cap door to clean and get the remaining water out of those areas (like cleaning under your arms and behind your ears) LOL!
I then go over the car with a blower to remove any unseen water that may remain in the cracks and crevices. This is what you see on your car after you've washed and dried it off (you thought you got all the water) and then drive it somewhere and then when you stop, you see water spots all over the car. I not only "blow" the car's body, but the tires and wheels too, after which I apply the tire dressing. After this I polish and wax the car.
To apply the polish I use a Porter Cable orbital polisher. This one won't let you "burn" your paint. I do a section of the car at a time, spreading the polish and wax around on the "2" setting, and for the polish, finish applying it on the "6" setting. This gets rid of all the swirl marks. For deeper swirls and scratches, you'll need to use a "stronger cutting" lower "grit" polish. For the wax, when applying it you leave the polisher on the "2" setting. For the polish and wax, remove by hand with a microfiber towel.
The last step after removing the wax is to use a detailing spray, high gloss synthetic sealent. This will bring up the gloss even more while also protecting the claying, polish and wax job you just did. You won't need to clay, polish or wax your car again for about another 3 months.
And that's auto detailing 101!
