My 85 Gibson has the original paint outside. I am wanting to paint the decks and would like to keep it looking as original as possible. Does anyone know how to do the speckled paint look on a Gibson deck? Also, all decking is solid and has no soft spots and doesnt appear to leak. However, it pops and cracks when you walk on the front after being away for the week. It isnt as bad after you walk on it a bit. What causes this and how can i quiet it? Or, can I?
