I thought I would take a break from the tedious work of removing fiberglass to a less tedious(?) task of removing the putty between all of the gaps between the planking. These gaps which I assume are there from the original build, are 1/8"+- wide. So when I canvas this I am again assuming that the white canvas will show through on the inside. I'm not sure I will like that. Is there anything I can do to the canvas to color it? Are there other solutions out there other than live with it?
