## Description

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

Review: I got this product to help in my battle against my landlord special of an apartment and it DID NOT disappoint. From cracks around doors and windows that the light shined through to the seam under a sliding door and so much more, this product did the trick to seal up the drafty spots. It’s super easy to use and reuse. Unless you’re really looking for it you won’t even know it’s there and there’s no foul smell to it either. It sticks well to itself and to whatever you put it on. A little went a long way for me! 10/10 would (and probably will) get this product again.
Review: Worked well to seal air leaks in my 4 seasons room. Super easy to use and not very messy. I already bought another tube. The cap comes on and off easily. Way better then traditional caulk

I am no handyman and definitely not good at DIY stuff around the House, but this practical and excellent product gave me the confidence to seal up my Window in my Basement and it worked flawlessly! I can’t say enough good things about this product! It’s easy to use and does exactly as the product claims and there was virtually no mess!
