I have not had time to sit and watch the whole course yet. It is 8 hours. I am in the 1st stage of my 72 Chevelle restoration and have not been find anyone to paint my car for a reasonable price so I have decided to do it myself. I have found what I have watched so far to be very useful. Being able to watch it over and over again is a great help. My only complaints are some of the audio is poor because of the compressor running in the background and when they are in the booth it is very difficult to hear what is said. I would love to be able to ask questions. I am following your suggestions on primer and metal prep and was going to media blast the car with crushed glass but have decided to only do the underside, firewall, trunk, and door jams. I am sanding the body panels because I have not felt comfortable with anyone knowing what they are doing in my area when it comes to blasting a car.
