I recently purchased a 60 year old home. While restoring, I have used Flex Seal caulking, spray paint and canned paint. All worked well , but will have to wait a good while to see how it holds up. Be careful to check the volume when you buy the canned paint. From the picture it is easy to assume you are getting more than you think. My favorite use has been filling in small concrete cracks. Buy a squirt bottle like ketchup comes in at a restaurant, pour the liquid paint in there and then squirt into crack. It is thin enough for gravity to pull it down into the crack. I continue to find uses and keep buying it, but I cringe at the cost every time. KNOW THIS! You cannot paint over it. Paint will not stick to it!

I used it to water-proof garage floor-level cinder block and the grey color is what I needed. It was easy to brush on and it really looks good.

I have an old galvanized watering can with internal rust spots that I wanted to use as a watering can and not a prop. 2 coats of gray paint on the interior over a lightly abraded surface and the can is now back to work, the rust protected from the elements. Going to do the same painting inside a watering can nozzle since it is painted steel .

Bought this to patch a leaking cement fountain where epoxies had failed. Coated the entire inside of the fountain with this, thickly, and it worked great. Looks pretty smooth when dry, flowed into the cracks. Solved my problem.
