The shrink wrap is pretty simple. Basically you would need just 1 tool, lord knows we always need more tools, but a heat gun either electric, which would be slow going, or propane, my personal method. The shrink wrap can shrink down about a maximum of 1/3 its original size, so if it is put on loose, it should be skin tight aftr it is hit with a heat gun. You would need seam tape to put your seams togather, obviously, and then the edges could be wrapped around a 1 x 2 furring strip or 1/2" pvc pipe which would be connected to the framing. I have done my old bass boat in years past twice and it was relatively easy. The supply place I bought my wrap from also had a rounded galvanized frame they did, so they could work in poor weather, and it was up for several years with the same wrapping. Keeping in mind that this was in Colorado Springs, before I moved to Oklahoma. The winters were colder, and wetter with a lot more snow, and the summer sun was much more UV intensive.
I did a quick check and there are several youtube videos on shrink wrapping Boats, RV's, and buildings.
