DYNAFLEX ULTRA 10.1 oz. White Advanced Exterior Window, Door, and Siding Sealant is rated 4.4 out of 5 by 190.

This last tube I purchased, when I went to use it, nothing but oil oozed out. Finally the caulk came out but it wasn't a consistent bead. It had separated or wasn't mixed thoroughly at the factory.

This was the worst sealant I have ever used , it came out of the tube runny and I ended up taking it all off and throwing it away . I will never use another DAP product again

The only thing to be careful with is that in applying it, it has a tendency to stain your hands if you're using the darker caulk. It is a water-based but it is still very strong and it has the tendency for the residue to cling to your hands and stay on your hands. Use gloves or white pants off with clean cloth regularly during the use.

When applying the product will splutter out causing a mess and the air pockets make it very difficult to get a consistent bead. When the air pockets pressurize and you release pressure on the tube, the product will continue to come out causing waste.

I usually buy the Dynaflex Extreme Stretch caulk but there were all out of it so I thought I would try this instead as it is just as expensive and the expensive caulks tend to work better and last longer than the cheaper ones. So far, it seems to work well but time and weather will tell.

Rated 1 out of 5 by from The. Worst. Ever. Has a consistency about like mustard. Good luck trying to run a decent bead! I think I got more on me, the walls, and the floor than I did on the target gaps. I don’t know how it will hold up and it doesnt really matter. I’ll never buy again - too hard to work with and too much waste.

The caulk had a milky liquid that keep oozing on some and the other tubes will continue ooze caulk out even with pressure removed. It made a huge mess and made it take 10x longer to caulk.
