Rated 1.0 out of 5.0 by MGS Disappointing -- will not dry
I purchased this product to caulk exterior gaps. During the application of this product, I was delighted and thrilled. The product feel and texture made working the caulk easy and enjoyable compared to a silicone. However, that initial jubilation and pride in my purchase decision was tamped raw as the product is not drying. Four days since application and the viscosity is no different than day one. The product did not skin and is not drying. Do not use this product. Use a tried and true silicone. The word premium is simply marketing jargon and false. I regret my purchase choice and I dread even more the looming clean-up necessary now to remove this product and use silicone.

I have used about 12 tubes of this stuff to seal up my 54 year old house. It works really well. I have used mostly the gray color as my house is painted gray.
I think alot of the bad reviews are based off of people who did not read the instructions. There is a BIG DIFFERENCE between the colored stuff and the clear. The CLEAR TAKES A LONG TIME TO CURE. It states right on the tube, the colored stuff is ready for paint in less than 4 hours, but the clear is 7 DAYS.
I have a bunch of tubes left and plan on using this exclusively on my house.

Rated 1.0 out of 5.0 by BSM Not good for exterior use in Colorado
Big disappointment. Used Dynaflex prior to exterior painting with various gaps and backer rod where applicable. Waited a few days for product to dry. Product did not appear to be cracking after cure time, but within a few DAYS of applying latex paint it began to crack. Regardless of application almost all of it has cracked, especially on the joints of lap siding which it was recommended to be used on. Would not recommend product for exterior use. At least not in Colorado. Only thing worse than paint prep is re-doing the work so soon. Will try Big Stretch and avoid this product in the future.

Rated 5.0 out of 5.0 by sdowney717 Very Good caulk, I used on my wooden boat sealing planks
I have an old carvel wood hull with mahogany planks. The OEM linseed oil white putty was badly cracked. I wanted to keep out the rain getting between the planks. So I removed the old putty. I primed with zinsser bulls eye primer the wood. Then I filled the seams with the caulk and smoothed it down with my finger. It shrinks some but that is good as I like seeing the plank edges on the hull. Then I painted white acrylic gloss Behr on top. It holds up, no cracks and no leaks since 2014. And you can sand it wet and dry to smooth the surface.

NEVER BUY THIS!!!!!!!!!!!!!!!!!This is horrible caulk. Takes a super long time to dry clear and as soon as it is exposed to rain it will turn white again and swell up from absorbing moisture. Strange why it is advertised to be a waterproof caulk yet absorbs moisture after it is fully cured. This definitely isn't my definition of waterproof! I use several thousand tubes of caulk a year and never had other caulk behave this way. Contacted DAP and they denied anything was wrong with the caulk after testing the samples sent to them. See picture of caulk samples that was exposed to a few days of rain after it was completely clear.

I used this caulk for raw wood trim and a wood surface in 60 degree weather. After several days this caulk is still not dry. Now I have to remove it and recaulk with another product. This is awful!

NEVER SEEN ANYTHING LIKE THIS .THAT IS SUPPOSED TO BE FLEXIBLE AND WATER PROOF. IT WAS NEITHER. I HAD TO REEDO ALL THE JOINTS AND IT WAS A MESS TO CLEAN UP.
WHAT A WASTE OF MY TIME AND MONEY.

Thought that this caulk would be a good choice to reseal around windows. Cleaned out old caulk and used 2 tubes to seal and fill minor gaps (less than 1/4"). Four hours later caulk did not form an outside skin. The next day it rained and dissolved most of the caulk. Had to remove caulk, clean it out of the bricks and purchased different product. No where on the tube does it say to not use if rain is in the forcast within 24 hours. Product only states that it should be allowed to dry 2-4 hours before painting. Temperature was in the 80's and 65% humidity. Returned product to Home Depot and explained issue. Home Depot refunded my money with no problem.
