I put a Guts cover on my old KDX 220 by using a regular staple gun. It would have been much easier with two people helping, but I managed to do it by myself and it turned out really well.
Just keep the cover stretched tight and aligned correctly and shoot your staples. I think I used 1/4" staples?
With a pneumatic it should be TONS easier than the regular old squeeze-handle type I used.
Iffn you don't wanna try that, I have also used an upholsterer in Fletcher. He's kind of across from Fletcher Feed and Seed and the car stereo place/post office (how confusing is all that?
I know Yellow Jacket has used a guy somewhere in Hendo/Fletcher too. PM him.
Good luck, I know you'll get er on. I'd like to know how you like it when you have time to review it.
edit: Love your sig line!
