I would underbase with a Black Bleed Blocker if you use HSA and plan for a full temp cure.
If you used the air dry catalyst (Warp Drive), you can probably get away with P/F/P of the Comet white and just cure at realllly low temps to get around the bleed issues with the Poly.
Just thinking kinda crazy here.... maybe use a hair dryer to get the puff effect going and still finish up with air curing...?
My main concern in all this, would be the Polyester bleeding, and Koozie material is notorious for that.
