Yeah I may be doing my frame about the same. One thing I'm going to look at is one of these special wands to turn your pressure washer into a sandblaster. Not sure how effective it will be but I think it's worth a try.
I hope you continue to post on how you remove the cab.
I will be sure to post some photos of removing the cab, etc. I've already done some preliminary work to get the cab off, like disconnect the pedals, wiring, and remove the steering column. Getting the steering wheel off turned out to be quite a fight. My first attempt to use a standard puller didn't go so well. I managed to damage the threads on the end of the column. I had the nut flush at the end of the shaft, but I had to put so much torque on the puller bolt that it walked off-center and forced down on the edge of the nut, ruining the threads (not all of them, thankfully, just at the end). Hitting the underside of the steering wheel with a dead blow hammer didn't do a thing. After some internet cruising, I found a photo (maybe it was on this site) of a puller that a guy made that grabbed the wheel from underneath (in stead of via the two 1/4" bolt holes in the steering wheel face). I made a similar puller and had the wheel off no problem.
