Filling Gaps Before Epoxy Seal/Flood Coats
First time poster here on the forum. (What a wealth of info!!!) I am getting ready to buy some Etex to begin my pour on my bar back and would like some advice on filling the more obvious gaps between my wood flooring planks i used for my top. I have read a ton of different approaches in regards to accomplishing this from wood putty to even clear caulk, which was Neuner's approach. I am leaning towards the clear caulk route because i feel that the wood putty will look bad compared to the natural wood grain. Have any others used the clear caulk approach, and if so was it silicone based? Everything I have read states that epoxy will not bond properly to silicone based caulks.
I have included a couple pics of my bar back progress and also a couple close-ups of the gaps I am referencing...
