Hello, I am very new to this so looking for some advise on what to use. I am building a Kitchen table with oak and poplar. Some of the boards have small knot holes witch I believe make the table look even better and we are going to put some markings and stress marks on it before using a natural stain. I am going to fill the knot holes in with a clear epoxy/filler but I have never done anything like that before so I'm looking for the best/easiest. We are not doing the whole table in clear just filling in the holes. Are any of the clear epoxys sandable just to get it smooth with the wood after being filled in or will it leave marks. Any info is greatly appreciated. There are so many brands to choose from with varying price ranges. Don't want to spend a fortune on something I'm only going to use a cup full of. Thanks again.
