I'm now on Medicare,officially old.
I've seen horror stories of guys losing interest due to the long term job at hand.If you find yourself in that position come to us and we'll give you a little ''push'' to get going again 
Out of curiosity, what is your process for cleaning the surface under there?

Out of curiosity, what is your process for cleaning the surface under there?
Originally I intended on sand blasting it but after reading stories of blasting causing severe warping, I resorted to mechanical methods.
Scraping the gunk/ undercoating, wire wheel on an angle grinder, scotchbrite pads on my die grinder, flap wheels, sanding discs and anything else I could find to get down to shiny metal with the rust removed. Rust gets cut out and patched.
There "was" a media blaster in our area that I planned to use but they went out of business before I could get my stuff to them.
After I have cleaned the area and before I put the cab supports on I rattle canned primer over the raw metal. Put the support in place and scraped away the primer so I could get a good weld. I'm sure some of the primer will burn away from the welding process but there is really no other way that I've found to do it. I made the mistake of shooting some undercoating spray in an area then welding. Let's just say it caught fire quick.
I plan to seam seal everything I can to make it as water proof as possible before undercoating after all the metal is replaced.

Couldn't you use a chemical stripper of some sort?
