I hadn't read the thread in a while ,, too bad, he didn't jump on it sooner

Well, if it were me, at this point I'd just sand it all down to as smooth a finish as you can get with 400 grit, don't worry about taking off all the paint. Wash it real good, Then overlay a layer of 5/8-3/4 oz cloth and resin as if you were glassing wood , sand it smooth, rattle can automotive primer, spot putty, etc. typical prep and paint to your liking. IMHO It's worth a try.
