This seal has worked well so far. It has been about 2 weeks since this was used to seal a leak in the ceiling of one of my vehicles and has held nice thus far. It has only rained once since applying this, but I have high hopes.I like that it came with different tips and gloves. I didn't even have to run it under hot water to thin it out. Great experience all the way around. I will be ordering more.

Although sold for automotive use, this can be used on a broad range of applications. Adheres to most materials very well. Flows appropriately. Paintable after curing. Also remains somewhat flexible after curing.

This seam sealer bonded very well on my auto body repair. it was pre-primed so I could use it on bare metal. It appears to be a good sealer. Fits nicely into my caulk gun. It comes with rubber gloves to protect my hands.

This white polyurethane automotive seam sealant is highly flexible and works great for sealing various surfaces. I used it on aluminum gutter ends, and it adhered well, creating a strong, watertight seal. It’s easy to apply, smooths out nicely, and remains flexible after curing, which is important for areas that expand and contract. The fact that it’s paintable makes it even more versatile. Whether for automotive use or other sealing projects like gutters, this sealant does the job well and holds up against the elements.

I ordered this seam sealer to reseal the seams on an old sports car I am restoring. The sealer flows easily from a standard caulking gun, even through the smallest hole in the supplied nozzle. For me this was perfect since I have some very narrow seams that I am looking to reseal. It was easy to finish with a rubber glove covered finger and the excess clean up easily with the wipe of a rag. One tube of this seam sealer is going to go a very long way.
