Good thick flexible coating. It does not get hard and brittle like regular caulk. Perfect for your RV or anything that might have movement.

Great to hear your project worked out.

Great product

Purchased 4 tubes as I am refurbishing a 1996 Terry trailer to sell as it has been replaced with a new TT. Product works as expected and flows nicely and levels out smoothly.

Good stuff

Works like a charm

Great purchase. You can literally paint this stuff on, which is great for narrow spaces. It can also be layered and adheres well to surfaces, even vertical ones. It does take time to dry, but that's to be expected in a damp climate. (It would actually be harder to work with if it dried too quickly.) Four tubes was more than needed, but this is a good thing too -- it's smart to have some extra on hand for the next time the travel trailer springs a leak.

What you need for your project:

1. Biodegradable soap and scrub brush to clean the surface.

2. Acetone and rags to give a final wipe before application. Can buy at any Home Depot, Walmart...

3. Utility knife to cut the the tip of the tube. Long stick to puncture the inner seal of the tube.

4. Caulking Gun

5. Disposable gloves
