At Mya-Moe we have been using the LMI white glue since the beginning. We typically bought a gallon every three months and liked it a lot. The last jug started to have problems so we contacted them and got the same excuse that everybody else did. We were a little upset that they didn't send out a "recall" notice to people, they just waited till you complained about it! The said it was still useable as an adhesive, but it just seemed too gooey and was difficult to spread.
We went out and got some tried and true titebond at the same time that LMI sent us the new formula. The new stuff seems fine but the entire saga reminded us that Titebond is easy to work with and dries hard. Yes, I know you can find research that shows it "creeps" too much. But, SO MANY instruments have been made from it that I am not worried about it.
Still not sure what we are going to go with from here on out, we don't like changing important things like glue brand without good reason. There are always un-intended consequences to the build process, we just want to make sure that it doesn't affect the final product!
