I'm also not a chemist, but have used different kinds of paint strippers to strip bottom paint from hulls and keels. I haven't seen any indication that paint strippers damage or degrade epoxy at all. But, a paint stripper that is too aggressive will definitely damage gel coat. It appears to dissolve it.
There are two basiic types of paint stripper. The type that you get in the home improvement stores is too aggressive for use on gel coated boats, but, IMHO, it might be ok to use on ungelcoated epoxy. I don't recommend that you use it, however, because there's a safer choice.
The other type of paint stripper is especially designed for use on Corvettes and other fiberglass bodied cars and boats. It is much less aggressive, and it won't hurt gelcoat. I have only found it in specialty stores that specifically sell painting supplies for automobiles. I haven't found it in the big, chain, auto parts outlets.
I don't think the first type of paint stripper will hurt epoxy, but I'm sure the second type won't hurt it, because Corvette owners wouldn't use something that would melt their baby. I have used it on my keel with no harmful effects, where I have used epoxy to repair and smooth the keel surface. I don't remember the brand name that I used, but I'm sure it's sold by different manufacturers.
