I'm chuckling at that one, Tom. I think I'd draw the line well before the pressure wash, however ;-)
Obviously, there are two camps with regard to washing and it's probably along the order of arguing about politics or religion in some circles. :o) At any rate, my slow progress with these rigs will continue to be documented as I progress. The chassis is now sitting in front of the picture window, waiting for the sun to return. It'll probably be a couple of weeks before I actually put power to it!
