I have a couple gallons of that stuff.....we did "authorized" Chevy redos on Avalanches and Escalades ( we did a few Rav-4s and even an Element) When we sold the shop, I kept the Gatorback. I have the product that needs a spraygun and compressor rather than the rattle cans, but it's the same stuff. It was developed in Melbourne Fla. to fix Chevy complaints. It will last at least 4 years that I know of 1st hand.....and that's in Fla with the heat etc.
Good product
***we shoot it thru a Binks #7 spraygun.....I wouldn't use a Sata or anything good
