I am drying out my rudder: I have drilled 3/16" holes in it about six inches apart.
I plan on filling the holes 3/16" in diameter with thickened epoxy. I have to then patch the drain holes further with glass mat according to the don casey book

I have a few holes 3/16" about six inches apart some 3 inches apart. How do I patch the holes that are so tiny with glass mat; i have done bigger holes but nothing this small. Anyone done this before?
