First things first. Don't bother trying to apply these products by hand. Get a dual action, variable speed polishing wheel. The dual action / oscillating version will be much less likely to burn the get coat and you can use higher speeds. I use one from Harbor Freight... $70 works great. Used it with their velcro attached foam pads, $7 each. Used a total of 9 of them. A friend of mine does detailing as side work and has used the HF wheel for 4 years now.
