I am making a Christmas ornament that has a body made from spalted maple and a cap and finial made from cocobolo.

All three parts were turned individually, wiped several times with denatured alcohol and sealed with two coats of sanding sealer. All three parts were then assembled with CA and I applied the first coat of “General Finishes Oil & Urethane” gloss finish.

After two full days, the first coat of finish has dried completely on the maple body, but the finish is still very tacky on the cocobolo cap and finial.

The cocobolo never remainder tacky with only the two coats of sanding sealer. Why is the top coat finish now not curing?

Any thoughts would be appreciated.
