Well honestly me too, I have only used pencil but if someone would donate a defogger kit or conductive pen, I would humbly accept the gift and use it..............

Seriously, the only hassle I have ever had is everytime I mess up my processor with AS and wash it in the sink, I have to re-pencil the bridges, but in all the times I have done it I haven't had a problem. Although, I have thought that maybe some of the problems people have with pencil is they are only trying to put a tiny line or dot of pencil. I go back and forth carefully over and around the bridges so that it is very dark and I have to blow off excess carbon. I just be very careful not to short my bridges together. I have had to erase and redraw, but I look very very carefully before I put it back on so I have never had to redo or have it stop working. But I think two months is the longest between washings I have ever gone, so I am not a real good source about longevity (never will be probably..
