Just make sure you do your sealing in the morning, before the wood starts to do its outgassing, or you get bubbles... Then moisture seeps under the sealant and the wood swells... Competely ruined what would have been a *REALLY* nice ig terrarium that way... But, I had some really nice wood to take out to the range for target practice...
