Homebrew PCBs

Someone mentioned petroleum grease dabbed onto the pads. You could
also put dabs of latex on them, it isn't messy and rolls off once it's
dry.

It's sometimes used in plastic model painting as a paint mask. Don't
pay $10 for a tiny bottle, though. There are other sources, at one
time you could get largeish bottles of latex at the hardware store in
the carpet department. I think it was a product for painting on the
bottom of rugs to prevent them from slipping.

And of course casting and prosthetic supplies. I just got a gallon
from GetSPFX.com for $35 plus shipping. RD-407
