Beginner with Eagle but not with PCB design.
I need pointers on implementing guarding (e.g., guard rings) using Eagle.
My current project is just two layer.
I have one signal entering non-inverting pin of an op amp I'd like to guard and drive the guard with op amp buffer output.
Thanks for any assistance!

Thanks for the tip on board coatings.
I worked on a picoammeter in the past using green board but can't recall how I worked around this problem.
To answer my own post:
I defined a new net class "guard" (8 mil) and used a dashed style to lay down the net.
Biggest problem is clearance errors if wrapping an input pin on an SO08 op amp package.
