I want to make a sound hole in a semi acoustic top, a rather intricate design, but I am worried that the hole will be of too smaller diameter for the clear to produce an edge, and will instead plug the hole.
Imagine a 1mm hole in a peice of wood, if you spray over it, it will probably just get filled, but a 10mm hole would not, the clear would stick to the top and sides.
So I'm staying whats the minimum width of a hole so that the clear will not cover it.
Sorry its kinda hard to explain.
