It's not even part us thinking you're arrogant, it's the fact that you ACT arrogant about your knowledge rather than just simply stating your facts/opinions & hearing our's out, as well.
I've used Liquid Nails & TiteBond I/II/III & I prefer Liquid Nails.. it seals very well, it bonds very well, not neccessarily on MDF, because MDF is NOT wood..
Birch, poppler and/or any other plywood w/grains, rather than a smooth surface, work quite well with Liquid Nails: Wood.
I didn't wanna post in here again because you have a "never wrong" complex it seems..
But yeah, I'll agree to disagree w/you as well..
