Alright, There are about 6 or 7 steps we will take. Let's look at some of the details of the work. Right now we have used the Meguiar's Clay bar.
The first step is to analyze your vehicle. Wash it good with a very good cleaning detergent. I highly recommend Dawn's dishwashing liquid for this. Do not use Dawn everytime you wash your vehicle, but for what we need to do here, it is perfect. After washing, use a lint free cloth to dry it off. I love the cannon bath towels for this. I don't know why, but they are great and do not leave a bunch of lint. I also do not recommend using those wool mitts unless you know it is clean and please keep it clean of sand/grit/rocks etc. or it will scratch the heck out of your vehicle.
Then in a nice lighted area, out of the sun, test the paint. The way I do it is to take a sandwich baggie or something like that and put my hand in it. Slide it across the paint, if it feels rough and sticks and hangs up, your vehicle needs to be clayed.
Take the clay bar, kneed it allot in your hand, in other words, roll it around like play dough and loosen it up. It is sticky, that's why it works. Use the detailing spray as a base spray, a lubricant. You want the surface to be wet at all times every where you are rubbing. It is going to make a mess, but don't worry, you will have to wash the vehicle when you are done anyways. Rub all of the painted surfaces and keep it lubricated with the spray. You will feel it loosen up and slide easily over the paint while doing this and move on, doing a small section at a time. I started on the top and worked my way down.
Even do your windshield with the clay. It will pull those bug guts right out. You know the last thing a bug sees when he hits your windshield, right? Well it's all over. After you have completely wiped the vehicle down with the clay bar, kneeding it all the time during the process, and you have done either your front windshield or like I did, all of the glass too, then take your vehicle back outside and wash it again. This time, do not use Dawn. It's too strong to use again. Use a nice soap that is made for vehicles, I am using Sonüs Gloss Shampoo on mine because that is what I bought and it is some dang good stuff. Then give it a good drying using a lint free towel.
1 WORD OF CAUTION - IF YOU DROP YOUR CLAY BAR, THROW IT AWAY. IT WILL PICK UP STUFF OFF THE GROUND AND GRIND INTO YOUR PAINT JOB AND RUIN IT. SIMPLY THROW IT AWAY AND USE ANOTHER. THAT IS WHY I HAD 2 OF THESE TO START MY JOB.
Next step, polishing with details and pictures.
Here is a picture of the box, the bottle, (which is very important) and 2 clay bars. 1 is new still in the package and the other is what it looks like after I finished with my truck. I used all of the spray up on this 1 job, if you do run out, just use some of the good soap diluted down with water to finish the job.
