You have to get rid of the all the bad, tar baby, epoxy before doing anything else.

Don't put more heat on it. You can lift the good stuff doing that.

Get some medium steel wool and lacquer thinner. Work on one foot square sections.
Wash and scrub it off until you hit the good hard stuff. Wipe it up with paper towels.
You will have it all off when you hit the hard shiney good stuff.

Do it outside, wear Heavy rubber gloves and a respirator.

Scrub the surface with a green scrub pad and water and dry.

Now you're ready to recoat.

Be thankful it was your last fill coat. If it was your first it would
be harder to get it all off.
