So I got started on my tank project this weekend. I got pine for my lumber assuming that I could seal it properly and wouldnÃ?¢ââ??‰â??¢t run into a problem. Has anyone else used pine and then sealed it? I am mostly done with the enclosure now, and I am looking for the best way to seal it. I guess if itÃ?¢ââ??‰â??¢s really not possible and will be a big problem then Ill shell out the extra money and rebuild. I was thinking polyurethane with several coats would be the best idea.
