spraying the bottom?

[warthog5]

George you've got the idea already. I flipped mine. I had a bunch more work to do to the bottom. I used a wreaker. It took about an hour each time and cost me $60 each time.
I mounted some cross bracing and 2inX 8in casters. I could move it around by myself, but it was much easier with another person helping.
