Just wanted to let everyone know I tried a Pilot Silver Marker, Extra Fine Point to touch up some traces before etching a board with the peroxide/acid method.
This marker can be found at Staples for $3 and is located with all of the other markers. (In my store it was on the right hand side on the last set of hooks). Interesting that I was NOT able to find this marker at their website.
The extra fine point worked well. I touched up traces that were .012" without a problem. I baked the board for 15 minutes at 150° F. Then immediately etched the board.
You will need paint thinner to remove your work, acetone was not effective.
Hope it saves you some grief!
