gunny,
Any of the serious methylene chloride based paint strippers will remove the epoxy coatings. IME it takes about 3-4 passes before a Browning epoxy finish is removed. Use gloves, the stripper will give you a chemical burn.

I did read a tip that I'll try the next time, which is to spread the stripping goop and then wrap the stock in aluminum foil and let it sit for 1/2 hour.
