The Brushing Liquid is kerosene and aliphatic petroleum distillate, and is for removing sanding residue from fiberglass or thinning Interlux Varinsh.

Shouldn't sanding have removed the amine blush?

Fortunately, I went a little heavy on the epoxy application, so I should still be able to do plenty of sanding, without damaging the glass.
