The plot thickens (like epoxy in hot weather)...

Our boat is covered in poorly repaired blisters.

Dang! It's always something, isn't it?

I'd review http://yachtsurvey.com/blisters.htm (again) before you
continue. Our 35 year-old non-epoxy is still fine, and epoxy has serious
drawbacks.

Because you already have a reveal coat, I'd stick with the current
color. No need to get confused whether a patch is the first or second
red layer.

And don't scuff for adhesion -- since there's not much to be had, it IS
intended to be ablative and the fresh coat will chemically etch and bond
-- but only slightly for roughness. No need to remove stuff that's still
good.
