Hi GreyFloyd,

I think you will need to sand the front of the body back. It must be glue (!) on there to leave those marks. I have never had much success staining on sanding sealer with FW products (I know others have which is why I tried, and tried again! on test bits of wood). Maybe don't go above 180 g sand paper before adding the stain (which is what some people on this forum recommend).

Just for interest - did you rub a damp rag (water, or metho!) on the body to check for glue spots?
