OK, I need to fill some countersink screw holes on the porch ceiling planks. I guess I need "wood putty" but I have found this stuff difficult to deal with when I've used it before. Wood is not my thing. It all says on the can "doesn't shrink, sands, sticks good". For me, none of it sticks well and it still shrinks. Is there a particular type or brand that works? Is it a matter of technique? What do I need to do?
