I’ve made a 10′ , ellipitcal table top for a “conference room” out of coumaru (Brazilian teak), unused flooring. I need a protective finish that can easily be repaired, if scratched, etc. I plan to use Zinsser sanding sealer 1st (does that make sense?). I’m not set up to spray; & am not that great with a brush, so a wipe on would be preferable. I know I’ll need several coats.
The other thing that I’ve thought about is, since coumaru is so hard, do I really need such a hard, protective finish?
I’d appreciate input from experienced woodworkers.
