Homebrew PCBs

i read a few threads and came up with an idea that i think ill try next 
time.

basically once you get the board done, take a Qtip and put a dap of 
petroleum jelly over the pads and then paint with spray of your 
favorite color (obviously non metalic paint...duh) and wait til it 
dries.  when the paint is dry simply wipe vigorously with a towel and 
the areas with petroleum jelly should come off taking the paint with it.

simple!!??

think it'll get 'er done?
