Re: OK, so I'm Sanding My Bottom...
I wasn't exactly recommending that. I was just recommending using a wide flexible piece of plastic instead of a putty knife. The thickened epoxy should be mixed just thick enough that it doesn't run or sag. If you can fair the epoxy as you put it on over 12" or 16" width the sanding will be a lot less than if using a putty knife.
