Using a Clay Bar

Do not drop it in the dirt, don't get any sand in it or it will make scratches. You will need to wax it when you are done too, results look nice

X2 on all that. Let the clay bar do the work for you and keep it well lubed. Don't use it on hot paint. I've been claying for years and love it. The results not only look great but they feel great.
