Here's what I remember comes with the kit:
-enough fabric for the whole airplane
-almost enough PolyTak glue for the whole project
-almost enough PolyBrush fabric sealer for all the brushed coats, but you need to buy extra for all the sprayed coats.
-you will need to buy the PolySpray UV protectant for all the sprayed coats.
-you will need to buy all your final color coats and reducer.
-enough reducer for all the brushed coats
-enough tapes, ribstitch lacing, stitch reinforcing tape, stitching needle, for the whole project. I did buy a roll of 3" bias ply tape (glad I did).
-you will need to buy all your brushes, MEK solvent, a high quality pinking shears (it comes if you buy the Kitfox tool kit), and heat shrink irons.
Its really a pretty complete kit up to the point you pick up a spray gun.
I will let others speak to the HVLP equipment because I had someone else do the spraying for me.
