Flex Caulk, Waterproof & Weatherproof Hybrid Polymer Sealant, Strong, Paintable, Indoor, Outdoor, Bath, Shower, Sink, Window, Baseboards, Door, RV, Roof, Wood, Auto & Marine, White, 9 oz, 1-Pack

I watched the video before buying. (I am elderly handicapped.) I bought one of these last year to seal cracks around an exterior window from the inside. I used the whole can to go around the entire single window. I have never used caulk before, but this was simple and not messy. I noticed some cracks in old caulk around other windows this spring and bought some more for them. Wonderful.

Ok, Id never caulked before so I wasnt sure how its supposed to work, but this was really easy! You just push the little thingy and it comes out in a ribbon. I thought I would need alot more than I did need, its good stuff!

Have applied once didn't work well am going to apply once again and will see results

Until it rains heavily I won't know how it works, but it did fill in the cracks. Will write a full review after I confirm it did the job. I hope!

Works great and very convenient. Much easier to get into smaller spaces with this instead of using a caulking gun.

Per instructions, I attempted to slowly apply the content but it was by no means coming out as a continuing flow. It was in lumps no matter what I did, the end result to seal the leaking window allowed more rain than normal into our solarium. Today, I will use Gorilla Tape to seal the window, not what I wanted but the water is damaging the wood and our Spanish Tile. Very disappointed

i really like this stuff, it does work very well. have purchased more.

This was exactly what I was looking for. A little expensive and came out a little fast at first but got it figured out and worked great.
