Dap 230
Easy to use. Color is drying a bit lighter than expected, but it's printable.

Great caulk
Great product. Dries slightly lighter than it comes out. Very pleased with the elasticity of it. Good price point.

Right Color, Right Price.
Being the color gray, It matched my solid color stain perfectly and now I don't have to repaint. Does the Job and I got it in time for my weekend project(seal every crack and crevice to keep the cold out and heat in!) Gotta prepare for the high energy prices this 22-23 winter!

Color is very light gray
This stuff works well but the color is much lighter than you think its dries very light and doesn't look gray at all. I'll post a pic.

Works well on stucco
I replaced the nails that attached downspout brackets to my exterior wall with screws and I used this product to seal the holes. It seals very well on stucco and prevents water seeping through. Although in the winter weather it takes a few days to dry.

Good price for a good product
Bought these to complete the repainting of my house. Good quality and durable. Have used this product over the years and it seals for a long time which means I do not have leaks nor to I have to continually reapply the product to maintain the protection. Saved about $2.50 on each tube by ordering on line.

Color not true - could not use
Picture shows a dark gray color. This is the color I expected and needed. The color I received is much lighter gray and is not close enough to be used in the DIY project I am working on. This is a case where buying it locally would have saved the cost and delay. The color depiction on the site should be more accurate.I'll try to find a place to use this where the color is not important or where it can be painted over.
