While I was varnishing the insides of my wing spars I usually ended up with extra varnish. I resisted the temptation to use the extra varnish under the cockpit floor not knowing if I would need to glue in a piece of wood for something. I had a moment of weakness and varnished the first 2 bays. I now realized that my rudder peddles will mount close to the first cross member and I will probably have to add a chunk of wood for the mounting screws.
How am I going to get that varnish off so I get a good glue joint?
