This Cadillac owner came to one of my seminars last year and remembered what I told him about how the dealers up charge the paint seal application. Lucky for him he kept my number. When he called me he said the dealer quoted him $875. He made an appointment with me and I did it for $175. It took me 3 hours, which included the following process. Pre soak bath/hand wash/clay bar treatment/hand wash again to remove residue from clay/my deep cleaner treament which has polishing oils in it as well. Finished with my sealant. I did notice some rail dust on the car which came off fine with the clay.
