Using MDS (I think it is, high end plywood looking stuff, smooth surface both sides, pricy)
with small cut outs of some kind of board...composed of sawdust, very flat, smooth, not as pricy...that I've gorilla-glued to it's surface....
and screwed in, counter sinking the screws.
It's for outside. It will be very well painted.
Will Bondo hold up as a filler in these holes?
Any thoughts?
thanks..Linda
