How to Use Liquid Sandpaper with Car Paint

What You'll Need
Liquid Sandpaper
Buffer head white
Pneumatic sander or hand polisher

Liquid sandpaper, which used to be called compounding, is a great way to bring out the best in your dull looking car. Using it on your paint will buff out scratches dings and little nasties that mar your cars appearance. It will also bring back the shine that the sun and bad weather has taken away over the years. Using this can bring back that appearance of shine and gleam that your car used to have.

Step 1 - Cleaning the Car

Before you start buffing you need to thoroughly clean you automobile. And I mean spotless clean. Anything that is left on the vehicle will cause the liquid sandpaper to pick it up and use it and that will scratch rather than remove the scratches. You need to wash it by had and scrub off all the bugs, tar and road rash that is on the vehicle. Wash it with a good cleaning detergent that will get all the oil and dirt off. Then rinse it. Rinse it again, and probably one more time. You want all the soap off. Then you are going to dry it by hand. Use a good lint free cloth. Make sure as you dry it that there are no little bits of anything left on the paint that will cause it to be scratched by the buffing.

Step 2 - Buffing the Car

When you select your liquid sandpaper, make sure you get a light grit, too heavy and you will remove the the paint. If you are using a pneumatic buffer make sure it is on a low setting when used. Apply a small amount of the liquid sandpaper to the buffing pad. Whether using your hands or a pneumatic buffer, go in even circles using very light pressure. Let the buffer do the work for you. Too much pressure will cause damage. Buff out all the places you want to. If it is only your hood, then do that. Or do the entire car. This will take time and should be done in the shade. You can also use this on your chrome parts to bring them back to life.

Step 3 - Finishing Up

Now that you have buffed out the car using the liquid sandpaper, you are going to use a very soft cloth and some clean water to remove it. You don't want to put any pressure on this cloth because it will only rub the liquid sandpaper more. Rinse it off thoroughly and then dry with another lint free cloth. This should have buffed out any scratches and little dings that are in the finish and on the chrome. If you wish you can further protect your car by now adding a good compound wax this make the polish shine and protect you from future damage. Make sure to rinse it all very carefully and let no dirt get in the new wax.
