Well I decided to remove the coil cover on my coil and spray some undercoat on the coil bottom. The project was going pretty smooth until...The coil slipped from the position I had it in. Things went a-flying. Coil, undercoating can and even my reading glasses. Reflexs took over and I grabbed for the coil before it hit the floor. I caught it but in do so I smeared the still hardening undercoating. A nice smooth job went too an ugly lumpy mess. So...My question is, how should I proceed on removing the undercoating before it completely hardens up? I tried to cover up the mess with a couple of extra coats but it didn't help much.
