I agree, I'd be wishing I had blasted the frame too, your so close you have to do it !
I've done blasting myself, still have the equipment, but opted to have someone else do the dirty work on my current project. The frame has already been done and I just dropped my cab & doors off the other day. Hears a link to my build and there's a link to the blaster that I'm using.

My truck will look very similar to yours, even the same colors, I was thinking about orange and white but decided to keep the original paint scheme.
Looks like you have a good solid truck to start with.
Good luck with your build !
