    Spray is a nice dull black. Did the under body of my truck and skid plates.
    It takes a day or two to really set up, I was rebuilding my front end when I did the spray.
    I took my skid plates and let the coating bake in the Arizona sun for a few days.
    It was bakes on and perfect. Great product, get some.

    I use these to seal the leaking joint where my screened in porch roof meets the house! It's leaked for years and it's almost impossible to get at without a cherry picker! So, I bought an extension pole for spray cans! It works well! Now, I put up a ladder and using the extension pole sprayed the seam where the roofs meet. Even though I m spraying kind of blind I was able to stop the leaks. I intend to respray it again this summer with remaining product -. Justcasca precaution.

    It's a great product, nice sized cans that go a long way at a great price! I ve bought this more than once and would buy again!
    Cans have a nice spray pattern. Tried spray flex seal. -. No good -. Cans had more if a stream than a spray.
