This product is fantastic for window caulk that gets a beat down from the hot sun and other weathering all year. It stands up strong and I will never purchase the cheap stuff for my outside trim again!

This is outside use,sticks to anything, handle with care should know how to caulk. Very good caulking.

Good for around the new windows I installed

Does not clean up easily. Be carful applying

This product may be good in a pro's hands....but I could not get it to lay down cleanly. It is very thick and difficult to smooth. In fact, the instructions say not to. But then it doesn't come out in a clean bead. Will it seal? Yes. Is it durable? It appears to be? But I had to redo everything with traditional caulk for asthetic purposes.

Would not stick to the wood just kept falling off

Good quality product but hard to work with and a very long time to harden. The label says for professional use. This is not a good caulk for an inexperienced user.

Best sealant for doors and windows.

I've been using OSI for well over 30 years.... When it comes to Windows...Doors & Siding OSI IS THE ONLY ONE FOR ME

Have been using this caulk for 20 years and it holds up very well. The color stays for a long time as well.

This stuff smells to high heaven so please make sure you use it outside only. I used it to seal up a replacement electrical mounting box in my vinyl siding. Very sticky. Takes a LONG time to dry

Why mess with the rest when you can use the best! Awesome stuff!

Excellent product, an effort to use with the caulk guns sold in store. I ordered a Albion gun online to use with Quad caulk in future.

easy to put on and seals well

Google product to long lasting caulking

This is a very good high quality pro-grade caulking,

Caulking easy to apply with higher ratio leverage caulking gun. Very flexible after curing to maintain seal.

Works beautifully. Color options available are perfect and is nicely covered when painted. Fairly easy cleanup, but follow directions and it will be much easier. Avoid allowing to dry on hands. A bit of a strong odor, but dries rather quickly.

Great for caulking a vinyl window to the masonry around it

The best caulk around.
