If someone is to use this board I have to fill the cracks and make it look OK. Would not be sanitary this way.
In this case I’m using casting epoxy.
Tedious work. If a crack goes all the way thru, I had to put scotch tape on bottom so the crack will fill up. This material takes 24 hours to set up and will run right thru and out bottom. But it will fill crack completely, since it is casting material designed to fill every nook and cranny.
As you can see here 24 + hours later sanded out you can hardly see crack. In picture thin darker line tapering toward you to bottom left corner.
Still need to sand out epoxy and round off bottom and then finish board.
