Paint and stuff

[Flyboy66]

Here's what I remember comes with the kit:
-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.
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.

How much more PolyTak and PolyBrush did you buy? What was the 3” tape for? Where do most people buy brushes, MEK?
Does John sell these items? I figure I would just pick up the extra stuff when I pick up the kit.
