I had ever used that stuff but I don't like it very much. Because it dries a little gummy and not very strong for C/L use though it would be OK for F/F use.
I have the same problem with all of the alternative aliphatic glues, and gorilla glue - they never get very hard and that makes them impossible to sand, they deflect while you are sanding, then spring back. Titebond II is particularly bad about it, it's like liquid rubber.
I like original Titebond and Elmer's Carpenter's wood glue over any of the new ones. Drying hard is not a problem, silicon dioxide sandpaper will still go through it like butter. Pica and the old white Luthiers glue also dried completely rigid.
I have the same issue with SIGMENT/Duco, to a lesser degree- too much plasticizer. I am sure it is tougher that way, so it might work better as an adhesive by being tougher, but that also makes it difficult to sand.
