Decorative edge caulking on timber table

[sawty]

Hi folks,
I'm sanding and refinishing this coffee table. it has a black caulking around the seams as a decorative feature. Could someone tell me what product I should use to refill this line? I'm thinking Timbermate or Gilly's beeswax filler stick in black. Any tips on the technique of re-filling this gap with a black filler?
Photos attached.
Many thanks

I wouldn't use Timbermate. It will crack and fall out. The reason they used caulk originally is to allow the middle panel to expand and contract inside the mitred edging. I would refinish the wood, then mask the join and fill the gap with Sikaflex Pro.

It was used in low cost construction in the seventies came in rolls, have not seen it since as said above a product such as Sikaflex pro
