Just to add to the mix, due to allergic reactions to regular CA I have limited myself to odorless CA for the past 5 years. In that time I have used maybe a half dozen different brands at widely varying prices. I have settled on BSI as the one that comes closest to regular CA. Good stuff that! But my experience with both regular and odorless CA, no matter what the brand, has been that bonding the harder woods (spruce, basswood, and sometimes even liteply) with CA is a sometimes thing. There are times when it just will not soak into the wood to create the bond.
