I have to tell you, if you are restoring a truck you WILL be buying a compressor. Just admit it and get the darn thing NOW.
And advice on how ever you strip it, do ONE AREA or panel at a time. Get it in epoxy primer and move on. DO NOT do the whole thing at one time, you will be overwhelmed.
By the way, medallionrefinish.com has Rubber seal 2K epoxy YES it is real 2K epoxy in an aerosol can! Part number RS587 I believe. I have a can in my car that I just got today to try out.
