I'm getting ready to make a batch of convex side mirrors (I know I've been saying this for a long time, but with Memphis coming I don't want to disappoint anyone. :-) I have heard that there is an aftermarket kit available to stick on the back side of mirror glass to make it defrost. I've check around and couldn't find such an animal. Can anyone say who sells it? Since the convex mirrors that I make need spacers behind them (because the DeLorean mirror housing is very deep), there should be plenty of room back there for a heater. This won't change the shape of the glass, but it could influence how I make the spacer. For those of you who are on my waiting list, I'm going to try to have them ready so you can have them on your car when you leave for Memphis. Otherwise you can see me there with the goods and I can make sure they are installed properly (but it isn't rocket science.) Walt
