I recently bought a small house that has that '70s wood paneling on 50% of the walls. I have heard of a fiberglass covering that goes up in 2 steps. Roll on a thick adhesive then put up the glass cloth, smooth out the bubbles and let it dry. It is supposed to fill and cover the groves in the paneling and be easily cut around windows and doors and paintable. What is it called, where can I buy it and is it the best thing since sliced bread?!?!?!?
