Rated 5 out of 5 by from Best brand I always look at other brands but then always buy "Dow's". It flows well, seals well, it's easy to smooth and it lasts. You wont need to dig this stuff out and redo in a year or so

Rated 5 out of 5 by from lowgee Flows easily and smoothly. Fine construction means it fills small cracks and crevices making a better fill overall. performance so far good only time will tell regarding reliability.

Rated 5 out of 5 by from Garden stream and waterfall re I required an environmently friendly mastic for construction and sealing gaps in my man made stream. The reviews seemed to fit the bill so I thought I would give it a try. So far it has been successful joining rocks and slate, filling gaps and the stream is now leak free.

Rated 5 out of 5 by from What I grab first I've tried several silicon's over the years but this is still my 1st choice for use in kitchens and bathrooms that I install.

Rated 5 out of 5 by from Totally recommend I believe this is the best silicone on the market. I have used many different types over the years and this is best for a long lasting professional level product. The only negative is the tip doesn't come with a cap, so once you have finished, any silicon in the screw in applicator can dry out and requires a bit of clearer out with a screw driver to remove. No biggie though and worth it for the professional looking finish you get with the product.

Rated 5 out of 5 by from Get the job done properly Excellent multipurpose adhesive This is always in my toolbox Forget the cheap alternatives Spend the extra and do the job once

Rated 5 out of 5 by from Perfect for my needs I chose this sealant for its inert properties as its used to seal a 6ft vivarium housing a boa constrictor. Much cheaper than some other online aquarium sealant most people use and does the job well from a well known manufacturer.
