Hi Katherine,
Im having a tough time with trying to put wood in polyester resin.
Ive tried different types and cuts of wood and they all seem to have a similar effect. The air bubbles seem endless.
Im sure that no matter how dry the wood seems, it will always retain some moisture. I assume this is the reason.
But is there a way around this? Maybe coating it? Or a method to completely dry it out first?
Thanks!
