Set of 4 Kevin Tetz Paintucation Series DVD

I ordered all 4 DVD's...so far I have watched the main one, "how to paint your car". I am familiar with the author from his various television shows. I thought it was a very good dvd. I only gave it a 4 star because it lacked more detailed/simple explainations of how to measure paint mixtures and didn't discuss what you might need as far as an air compressor.
