Been sitting on this idea for months. Somehow wanted to line/cover the bottom of a canvas bag so it is more rugged/waterproof. Wanted to use some kind of truckbed/rhinoliner/herculiner or similar. Truth is it works for impact resistance on flat surfaces but cracks when flexed. See my test material below. Not suitable for this application. [so you're posting about stuff you haven't done now?? -ed.] At the last minute I held off... Not even going the waxed cotton route. Keeping as is. Close one...
