I hit the top of cab with my belt sander, steady hand and plenty of nerves. Came out pretty well, did not take a snap of when I rechecked, but its a lot better, you will see when its back together. After that I taped up cab and BB and gave a
few problem areas a hit with spray putty. Will see how these come out when I sand back. though I suspect the BB back panel will need more build up.

Cheers
