I have used this quit a bit. I have not had any of my joints come apart with this glue I like to use it with oak and walnut it is a good blend for color when gluing the two together. I also make my own wood filler with it by using sawdust from my sanding. I have found this to make some seamless joints. I do find when used with lighter woods it is a bit dark. glue does need to be used in a timely fashion or you will be just throwing it out. I actually refill my friends bottles with the gallon sharing the cost. If it starts to lump I use it up quickly and give it away to my friends. A smaller bottle would be a better buy if you do not go threw it in a couple months or so.
