Rust Bullet - Coating for Concrete - 1 Gallon Metallic Grey

Our garage is 45 years old and approximately 380 sq. Ft., and thus we ordered 2 gallons of Rust Bullet, along with 1 quart of the recommended spot treatment. We should have ordered 2 quarts of the spot treatment, as 1 quart only covered 1/2 of our garage (we chose to use a similar product from Home Depot for the spots on the other half, rather than delay our project to place a 2nd order). We followed all instructions and one gallon of Rust Bullet provided full coverage for the fist coat. There was a very small amount (less than 1/2 inch) of product left from the 2nd gallon after applying the 2nd coat. We spoke to a representative from the distributor regarding how to handle a significant 1/8 to 1/2 inch Crack down the middle of our garage floor. They strongly recommended the use of SikaFlex, after the Rust Bullet had cured for 72 hours. We followed this advice and are extremely happy with the outcome of our total project. I had painted the ceiling and walls, before starting on the floor, with latex paints. Rust Bullet fully covered all of the drippings/spots from the wall/ceiling paints. My wife says it looks better than a brand new garage. Now we begin normal usage and see if the product can stand up truly stnd up to this usage for up to 10 years. We purchased SikaFlex at Home Depot and filling our Crack required 2 and 1/2 tubs. Sika manufactures many products, but SikaFlex comes in Caulking tubs. The product comes out kind of runny, but then self levels into the Crack and begins curing within a couple of hours.
