Media blasting is the process of propelling media particles from a blast machine using the power of compressed air. This converts media particles and compressed air into an effective cleaning treatment that takes skill, properly engineered equipment and good judgment. Each component contributes to the overall performance of the system.

If you really want to give your car a "physical' or just want to know what a car has been through in its lifetime, strip the car down to bare metal as we did with this 1964 Chevy Impala. You'll be able to tell if the car has "cancer" or rust, or if you have to do patch work to it. Let us give you a warning! This process is almost like going to the doctor; you might learn a thing or two that you didn't want to know, except here you don't need to worry about lube or a white plastic glove!

This Impala was supposed to be almost ready for paint. It just needed some light body work and to be sealed in primer. Wrong! Since the car was in storage, we had enough time to check it and see if there was something more serious going on with the body. After noticing surface rust bleeding through, we couldn't take a chance so we had to investigate. We went to see the "doctor," in this case, the media blasting company, Blasting Specialties in Santa Fe Springs, California, where Lee's recommendation was to take the car down to metal.

It seemed that the '64 had a few things wrong with it. First, it was left bare and exposed, so rust had accumulated on the body. Second, according to Lee, the car was sealed in the wrong primer and the rust had bled through. We also found out that the firewall had more than 1/2-inch of body filler and was not molded correctly. There were rust holes covered with tape and undercoating. To our surprise, the previous shop that had their hands on the Impala didn't do the job right.
