How is this better than other epoxy products? Specifically, west systems epoxy?

I don't think there's anything you can do with this that you couldn't do with WEST System if you were determined enough, but it certainly wouldn't be my first choice for smoothing a 3D print. This stuff is very runny by the standards of epoxy, which lends itself to very thin coats that are less likely to build up in small crevices and wash out fine details. That said I'm sure it's also nowhere near as good an adhesive.

Does this product effect the overall dimensions/tolerances of the print? Enlarge or shrink features?

It is a coating that adds appreciable thickness. It will enlarge all external dimensions and can cover up fine features if not used carefully. The effect on tolerance can be reduced by applying thin layers and sanding any remaining grain down.

Type of paint suggestions?

Acrylic / enamel paints work best.

This is a very random question, but can this epoxy also be used to seal cracks and knots in wood?

Our Tarbender may be a better choice for this - it is designed as a bar top epoxy, thought the XTC-3D will work as well, the Tarbender is a clearer material.
