    The Silicone worked well

    Good product but.........not so good coming out of the tube.

    I tried the silicone today and thought that the product was good, but doesn't stop comig out of the tube when my gun is released. It really is a problem as you're rushing to put the caulk gun somewhere so that the dripping silicone doesn't make a mess. It's also a waste of product. I've dealt with tubes like this in the past and it was all tubes acting this way, not just a few. Sorry, I don't think I'll be purchasing anymore. Response from SD: We apologize for any inconvience this may have caused. The Pro Grade 6000 series has a mildew resistant additive which makes this product a little thinner than your 100% RTV silicone sealants. We have sent out our premium to see if this is a better product for you.

    Great product. Cheap price.

    I always order my silicone from here because it's a lot less $ than home improvement stores, but it's still a great product.

    Great silicone

    This silicone was just what I was looking for! I needed 100% silicone sealant that is slightly thinner than typical off the shelf silicone and this was perfect!!!
