Thanks everyone.
I could do Danish Oil. I have actually done a bass in Danish Oil so I know what I am doing. This is unusual for me.
Utile looks like it could be nice but depending on the plank (like all wood I guess). I have some Sapele (similar apparently) planks for handrails and they are a bit bland. Dunno. But I do appreciate the input though.
The Epoxy thing looks interesting but for a 6ft table top it looks like a pretty specialist thing to do given the heating needed (according to YT) etc.
Corian is nice, but it is not wood
