Just used WD40 inside a stage light -- high temperature, WD40 = flammable. Now what?

Yeah... I feel like a complete moron. I sprayed WD40 inside a stage light because it was so rusty -- I wanted to lubricate it. Put the halogen lamp in -- 500W, 120V. Turned it on, worked great. A few seconds later I see smoke. After ten minutes or so, I realize it's coming from the WD40, which also happened to make the heat-resistant paint I sprayed on literally melt off of the light. I looked it up online, and I found out that WD40 should NOT be used around heat, sparks or anything that can ignite as it's flammable. Now I've essentially screwed myself over. How do I solve this dilemma? Do I try to remove the WD40, and if so, how? Or, do I alternatively just paint over the WD40? Any ideas? The temperatures inside the stage light probably exceed 120 degrees, by the way -- just saying =D
