I siliconed the inside of my box to make sure it was air tight.
Well guess what the silicone did not stick very well to the mdf. If u rub you finger accross it will peel right off.
I used door and window silicone.
So I said F$CK and took my time and peeled all the silicone off and sanded it smooth.
It looks like the silicone did not dry on the underside. it left the wood damp looking when it came off.
What went wrong?
