Hmm, probably going to start an argument here, but I'd be confident in saying that an enamel will be harder than an acrylic finish, and will stand up to abuse better. Enamels tend to soften with contact with hydrocarbons such as fuels and alcohols, but iare otherwise very hard wearing. That's why the goof off stuff was the wrong choice.
Enamel takes longer to go off, and tends to set from the outside in. Acrylic dries from the inside out, and dried much quicker.
Enamels sometimes have a yellowish tinge after time.
The auto stuff you get in Australia car shops for body panels will almost certainly be acrylics.
This info comes from respraying vehicles more than guitars, but I'd say that the same should be true on timber.
I like the Cabots range of polyurethane clear. I have used this over acrylics with no issues, and does make a good hard covering.
