Restoring teak cockpit hatches

Restoring my teak cockpit hatches
The wood core of my teak cockpit hatches had started to rot so I wanted to replace it and reuse the teak.
The boat is a Hallberg Rassy 26 from 1978.

Finally found a video doing what I want to do! Questions: 1) what backing material were you using for the repaired lid? 2) what sealant were you using? 3) has the repaired lid lasted well since you repaired it?
