Flex Seal LiquidRubber Coating Sealant, Waterproof, Flexible, Breathable, and UV Resistant, Roof Repair, Basements, RV, Campers, Trailers, Marine, EPDM, Masonry, Black, 16 oz

This stuff is amazing. I actually used it on the floorboard of my vintage VW and under fender wells. Very durable product and good sound dampening, I used paint brush and paint on very thick. Worked great and basically put a solid layer of rubber on my car for good protection from elements.

Sealed leaks around gutter seams, works as advertised.

I should be a spokesman for Flex Seal. I always have everything they make in all of the colors on stock and when running low I stock up like I just did. This stuff is amazing. I know from using at my home, our camper our sheds just how well this really works. I have told so many people about this they all stock up as well. A few years ago a tree branch came down thru my shed roof. We had to cut the branch just to get it out of our shed. Well I grabbed my ladder, Flexseal tape and spray and went to town. 2 years later it is still holding well. I can't say enough

The product was great as usual, can't really beat this stuff. Amazon shipping.... We'll, that wasn't so great. If they would've tossed the box 1 more time, it probably would've spilled all over their truck. Do better.

Great product. I used to seal the rust in my drip pan for my AC units.

Works

Two or three years back, I 3D printed some drink coasters to use. But one problem was that they would slide easily.So I ordered Flex Seal in this week to try coating the bottom of them creating a non-skid surface.It takes 48 hours for this stuff to cure completely. But after 24 hours with my 1st test, it appears that I am getting what I wanted. A non-skid surface on the bottom of these coasters.The stuff states that it can be used as a sealant. But there are many products that can be used as a sealant, and this 48 hour cure time is a drawback. 24 hours before it is safe to handled.It also states that it can be used as liquid electrical tape. Again, I agree with this. But that curing time is a drawback.But for coating surfaces, it is a winner in my book. (So far....)Update: April 9, 2018The stuff worked great on the PLA plastic coasters. PLA plastic is a material made from corn.However, I had 3D printed 1 coaster with ABS plastic with a rough base. ABS plastic is the stuff used in cars. Here the Flex Seal appeared to cure in 24 hours. However, that coaster required 2 coats of Flex seal because it had soaked into the plastic..Having used my coasters with the Flex seal bases for a few days now, they work exactly as planed. Put a cup in them with any liquid, and they are planted and un-moving. They won't slide off of a table without a lot of help.I suspect that this application would work for many materials where you don't want them sliding around.(Hmmmm...... I wonder if I can make some non-skid pads under my old laptop? Maybe the same thing for my sound speakers on my desktop or TV? It's an idea...)

Works ok but if you lay a thin layer it will peel and come off easily
