After my last build, of IPE/Boo, I did with TBIII, I think from now on I will only use Urac for projects like this.
I can't say it failed, but noticed during the transition between winter/spring/summer (yes took em a long time to finish) I had glue creep. Some days when humidity was bad, I would feel the transition between boo and IPE. I would sand down flush, and feel it again later.
Maybe I should have sealed the combo earlier. But I will only use Urac from now on.
