haha "better" air compressor is right, here's the one I used:

Needless to say, it hardly cut it. I actually started on one side of the truck one day, got impatient and stopped. I could only go for like, 10-20 second increments, then had to stop and wait for the compressor to keep up. Then one day I just did it, overall wasn't too bad. It was actually kinda fun.
