To repair or not to repair, Matrox G450 Dual

[CrackRabbit]

Over the weekend i got a sweet deal on a Matrox G450 Dual, 32mb, unfortuneatley there seems to be a problem with it, it apears one of the leads from the agp slot is scratched, i know there is the possibility of repairing the lead using a conductive pen and a steady hand. but what i dont know is what the concequences of this are, or where to get a very fine point conductive pen.

Please HELP!!!!!!
