Customer Reviews for OSI 10 fl. oz. #341 Clay QUAD Advanced Formula Window Door and Siding Sealant (12-Pack)

The color on the OSI website did not match the color of the caulking we received. We had to return the product to the Home Depot store and they allowed the return promptly. I have no problem with the quality of the caulking but beware that the color chart is not as accurate as we had hoped. I am going to call OSI and see if I can send them a sample of the color I need.

We have used this product with our Hardie plank. Also, works well with other caulk needs. Color matches well with our paint. We chose this because it was recommended by industry people not associated with this store. This was recently applied, so cannot say how the long term track record may hold.
