I should be able to paint the epoxy over the herculiner on Saturday. Cleaning all the old silicone off the glass has turned out to be quite difficult, however, cleaning it off the herculiner is easy since it peels right off leaving no residue.
As for cost, I was keeping track, then when I started crying, I stopped. I would guess that when it's all said and done, somewhere between $2,000 and $2500.
