Ca is CA, I have the little tubes I buy at the dollar store in my flight box and it works as well as any of the others. I buy brand X in 8 oz bottles at Hobby People and even at the wood workers Emporium. Never found any difference from brand to brand. None of my panes have ever fallen apart. I build so much I just keep refilling an old 2 oz bottle from the 8oz. I really like the wood glue sold by GP. Not sure who makes it but it really has a long shelf life. I bought it years ago and it's still fresh.
