## Description

Flex Seal Liquid 1 gallon White

Review: Easy to apply, does EXACTLY what it's supposed to!!! - Was unsure about this stuff, but I couldn't be happier!! Used it on my 30' tuna boat top, it had pin holes in it and cost $2500. To replace, and for $107. I'm sure I'll get several more years out of it.
Review: 46yr General Contractor, this product is INCREDIBLE! - I have been a Licensed General Contractor for 46 years. THIS PRODUCT IS OFF THE CHARTS!! I would give it a 50 out of a 10. If you line a plastic bucket buy painting the interior it does not permanently stick. Use like a ice cream pale, wait for it to dry and peel off. You will see just what it does. PREPARATION is MOST important. Get down to bare metal IF possible. DO NOT APPLY IN ANY SUN!! The cooler the weather or conditions it is MUCH easier to apply. It will dry finished in 24hrs but I would wait 48 hours. IT IS RUBBER. You could even make rubber products if you used molds. It cannot be ANYMORE waterproof. INCREDIBLE PROCUCT. I did NOT use the spray and probably would not. I used a 1" disposable brush and a 4" foam roller work EXCELLANT. Do NOT clean brushes as its not worth it. IF you need to get it off hands or anything it comes right off with a rag soaked in paint thinner, while its wet. I am in California with NO humidity so being in the midwest it would probably take more time to dry dry. A gallon will cover litteralley150 sq ft. I had some paint that would not power spray off and another product that was difficult to grind off and yet it covered very well. I rebuilt a swamp cooler built in 1985 because the quality of it is 50 times better then the junk made now. I had to make some new metal parts. I AM SO HAPPY WITH THE END RESULTS!! I have NO DOUBT it will last another 10 years if not more. It skims over and AIR cures it. SO...I bought a gallon and put it in used margarine tubs which had lids. As long as air is getting to it, it IS CONSTANTLY CURING. Have fun.
