Andrew,
I think the rule is clear that removing the paint does not change the basic ops of the motor. But like I have said many times before, if the Chalupas (or any motor) are overheating they are a symptom not a cause. Hot motors indicate a problem somewhere else. Fix the problem. When the case of the Chalupa is hot, think what the temp might be inside at wire level.
When the case is too hot to touch, you have already sacrificed molten varnish to the electrical gods. There is no coming back from this abuse and no amount of external cooling is going to save the motor. The internal temperatures, melt the varnish insulation, run the lubricant out of the bearings, distort the armature plates and shaft, and breakdown the internal adhesives used to keep all the parts in alignment. Remember that the only conduction path from armature to outside world is the shaft and bearings. All other cooling is by convection or radiation which is a slow process.
