i spent about 3 hours yesterday washing my car and waxing it, i was going to buy a clay bar and use it. The results were good, but im guessing since u've used the clay bar it turned out really good for you. I have a black truck and i dont think its ever been clayed. can u tell me how to use it, what the tips are and how much the bar cost?
In my experience Auto Magic seems to be the most readily availible brand. Some places sell just the bar in a plastic storage bin, others sell the kit with the attached spray bottle of "lube".
Me personally I use the blue AM bar. The red one is a bit more abrasive, but also harder to come by. For the lube, I use Meguiar's Quick Detail spray. There are other products as well.
Goes like this:
1) Wash car with strong soap. You want to remove any wax that might still be on the paint. For this occasion only, I use Dawn dish soap. It'll be squeaky clean when dry.
2) Tear off about 1/4 to 1/5 of the bar. Mold it a bit to sort of resemble a small burger patty. Light to moderate spray of the lube onto the painted surface. Within that sprayed area rub with LIGHT pressure. Enough pressure to move the clay across the paint will be sufficient. Keep working the area until the clay slides almost effortlessly across the surface.
3) If the clay starts streaking or skidding on the paint and out of your hand, you need more lube. You don't want contaminents in the clay to scratch the paint. Check the clay OFTEN, you'll be suprised at how much and how fast the clay gets dirty. When that happens knead the clay such that you can get clean clay back onto the surface. If you can't "make a clean spot" toss that wad, and grab another off the bar.
4) You know you're done when you can't feel ANY imperfections in the paint. No stubble, bumps, snags, etc. After completed the paint might look a bit nasty with the dried lube. No problem. Just rewash, or wipe down with water and a microfiber rag, or your quick detail spray. Your vehicle is now wax and contaminent free, and ready for polishing and waxing.
One full bar of clay will usually do 3-5 vehicles, depending on the condition of your paint. YMMV. Good Luck!
PS, My bad on brand name. It's Clay Magic, and apparently they no longer offer the red clay. Their website shows you everything. I'm not intending to promote this brand over say, Mother's or Meguiars, just sharing my experience.
