Rated 3 out of 5 by from Color is lighter than indicated Love DAP 230, great product. Tried the grey, and it is much lighter than the nozzle by 1 or 2 shades.

Rated 5 out of 5 by from My Go to Caulk This is the only caulk I use except for below the waterline on our boat and for concrete work. Indoors and outdoors it works great.

Rated 4 out of 5 by from I would buy again but . . . . I have read comments indicating Dynaflex 230 absorbs moisture after drying, does not dry within the time frame published by the manufacturer, and you cannot apply paint until well after the manufacturer's specified time. OK, maybe some validity to those comments, however, drying time is based upon ambient temperature and humidity, and the moisture content of the surfaces upon which the caulk is applied. If the moisture content of the surfaces is high, and if the temperature is low, and if the humidity is high, the product takes an extremely long time to dry. If the moisture of the surfaces is low, the humidity is low and the temperature is above 75, then the product dries per the manufacturer's specifications. One note of caution. If you use a colored caulk outdoors, and you do not plan to paint over the caulk, do not use this caulk. Even after days and days of drying, if the caulk is exposed to rain the caulk surface will turn whitish. If you apply this caulk under low humidity, warm or high temperature conditions, and the surfaces are pretty dry, and you plan to paint over this caulk, this caulk is great!

Rated 4 out of 5 by from All purpose sealant that works I've been using this product for a general purpose sealant for at least 5 years and have been very pleased with its performance against the weather conditions in Florida. I would recommend this product anytime for general construction

Rated 4 out of 5 by from Boat Cauking I used this product to seal the transom on a 14ft. aluminum boat transom . It worked great.

Rated 5 out of 5 by from The trick is to let it dry thoroughly I have tried scores of caulks over thirty years of home maintenance projects, I have settled on Dynaflex for most interior and exterior uses, with the exception of places I know are either going to stay really wet, or need to be painted quickly. DAP's Sidewinder works well for those caveats, but it's harder to clean up and it doesn't finger tool as well. I'm only writing this review because someone was asking me about caulks today, and I couldn't quite think of "Dynaflex" since I didn't have a tube of it handy---so I checked DAP's website for the name, then came across the review from the person who had trouble with paint adhesion. My guess is that the gaps were wide enough to need a little extra drying time. I wait until the whitish color goes away completely, then it's safe to paint. It's flexible, it's easy to work with, it doesn't reek, it's easy to clean up, and it's relatively inexpensive.

Rated 1 out of 5 by from paint won't adhere We replaced siding trim on a back porch exterior with Hardy board and used this caulk to seal all edges and holes. It dried overnight and the next day we painted with Sherwin Williams Emerald exterior acrylic latex paint (very expensive), and it would not cover the caulked areas. Everywhere we caulked the paint bubbled. After painting the caulked areas 4-5 times, the cover was finally almost acceptable. We will never use this product again and are returning what is left to the store.

Rated 5 out of 5 by from GOOD STUFF! As a General Contractor I have tried many caulking products over the past 25 years and I have to say this is my go to caulk. I not only use it on exterior projects but it also works great caulking in backsplashes and trim components. Have also inspected projects several years after completion and the caulking still looks great.
