Review: It worked for me! - I’ve seen ads for Flexseal products and thought they sounded too good to be true. I recently had to repair the vinyl floor in a car trailer. It’s rarely used yet some of the vinyl flooring was torn and otherwise damaged. I have been looking for a cost effective repair, with no luck. On a whim I ordered some of this Flexseal putty. It worked perfectly for this application. I basically wanted to cover the damage to make it less noticeable. It far surpassed my expectations. I now intend to go back and make the repairs more carefully and expect the results to be close to the original.
