I have some LePages yellow carpenter glue and I thought it was great. To the point where I built a small sub box, glued and screwed it and then removed the screws. It held together great except for one side which saw some stress when I had to move the box around sometimes. It eventually separated. That disappointed me.

 

Don't most Urathane based glues depend on humidity to kick off? Last time I used Gorrilla glue, it was suggested to moisten the bonding surfaces slightly with water first. Dunno if I'd want to do that with MDF

We use regular normal yellow carpenter's glue... Probond I believe. Works nicely.

Of course, it is starter season, so screw any woodworking until Feb. or so.... time to make some money!
