IT WORKS!!

It's works just as it said it would….. I suffered with a leak during rain on my sunroof and when I say 10/10 it's 10/10. Now I recommend using gloves or something to protect your hands because it's a hassle to clean up if you mess up

Although I get a 10% discount at a home improvement store the Walmart store was 10% less and they had same day delivery from a store. I have to depend on public transportation which meant I could not order from Walmart until I realized the Walmart price plus the same day delivery made it a great deal and an automatic yes.
