i bought this sealer to seal my backup camera on my truck. The black color is glossy and good looking while sealing my camera from the weather and moisture ( my last camera only lasted a year). I would highly recommend this product to anyone that wants a product that will blend in with the plastic...see moreof the reviewer's review

It was used outside around basement and foundation in Illinois during September. It rained for 2 days in which we had a few leaks the spray and the liquid did exactly what it says. A few days later it rained...NO LEAKS. I recommend the spray can as well as the liquid.
