bar clay is easy. Spray on some detail mist (which works like a lubricate), form the clay into a pancake and then rub down the area like you are putting wax on the pannel. Then wipe down with a towel. The bar clay will pick up a lot of the junk that sticks to the paint that you can’t remove with water and your wash bucket rag.

I’m also a big fan of the California Water Blade. It is a squeegee for your panels. I have a knock-off one I picked up from Walmart for under 10 bucks.
