[sdiy] etched PCB failure....

[mark verbos]

Hi!

i etched a photo sensitive PCB and it didn't work out all that well. 
there are many places where small scratches cut traces. Normally I just 
all a little piece of wire tot he board to jump over these sections. The 
problem is that some of them are in smaller places where this is not 
practical. i have considered throwing this one out, but it is a big 
board (35x16cm), double sided and was quite expensive.

I've heard about these copper pens to fix problems like this. How well 
do they work? what brand is "the one"? are there any other options? I 
would hate to just waste this thing.
