 Is there a way to fix small imperfections? Unfortunately, we don't recommend spot fixing for the simple reason that it's actually very difficult to sand out a small area if you've had a fly, a hair, a dust particle land in there and to actually pour another coat over top without there being a seam that's very noticeable. So instead, what we recommend is you sand down the entire surface and pour another well-mixed, well-measured coat of resin over the entire surface and that way you'll get a seamless, flawless finish.
