A low build epoxy on a timber such as mahogany would be excellent but would be more problematic on teak, as it has a high oil content, but is still possible after 'washing down' with acetone. If you use a SP or WEST resin neat (without filler), around five coats, it would seal the wood completely and look beautiful. Downsides are some care would need to be taken to roughly maintain shape if removing them and they would need to be over coated with a two pack varnish as base epoxy is UV sensitive. Such epoxy is extremely easy to apply and is simple to touch up if damaged after abrading but don't forget to reapply varnish on top!
