In this video, I talk about the pros and cons of both the Air Force Master Blaster by Metro, and a standard electric leaf blower. I give the insight that I have from using both devices for a few years. You may find my conclusion surprising so kick your feet up and hear my take.
One thing that people like to suggest is the use of compressed air. Compressor tanks have a nasty little habit of collecting dirt and water in the bottom of them. If your compressor lines are not properly filtered and the tank and filters are not checked and maintained often, you risk the chance at sandblasting your paint with debris. NOT a smart scenario. Compressed air can also do damage to emblems and decals if you get too close to the car. Thus, I never recommend the use of compressed air to dry a car with. I know first hand how much of a hassle it is to maintain pneumatic lines as that was one of my responsibilities at the Motorola depot that I worked for years ago. No compressed air!
Another thing you must take into consideration if you plan to buy a Master Blaster is the amperage that the unit draws. You must have a 20-amp outlet to use the device at full tilt or it will shut down the line that you plug it into. It draws a hefty 19-amps on full tilt so understand that before you plug it up and turn it on.
