It all depends on the job you do. You should deffinatly look into something more permanent. Here is a good article on how to do it with a DeFogger Pen.

There are many different techniques though. Look around and see which one works good for you.

Defogger stuff works great! here is a little tip, let it sit out for a few minutes to allow some of the clear liquid(water?) to evaporate off. You can use plastic or wax paper for this. After a few minutes, you don't have as liquidy of a substance, and can "draw" more than paint, and keeps the stuff from going everywhere. I could never get it right until i let it sit out, after letting it sit out, i got it the first time!

I used a common 'mars lumograph' pencil and it has lasted for several months, but go for the defogger kit if you want to be sure.

mine's worked for over 6months.

My pencil trick is still good after three months since I got my chip. you just didn't cover it well enough.

mine is still ok after 2 months, may do something to get it permanent soon as it failed.

Not very long. Silverpaint kicks butt.

My pencil trick has been going on for about 4 months but just in case i've bought some silver conductive paint from electrolube. I think that should be ok if the pencil job decides to screw up.
