What is the best way to achieve a grey wood finish? Should I use a grey veneer or can I stain certain woods to give a grey finish? I am making a small table for my son, in the shape of an electric guitar. The top will be plywood and will be sprayed to match his guitar which has black edges fading into a grey wood grain in the middle. I’m not bothered about matching the wood to the guitar, just want to get a similar look.
