    Good product. Used to seam seal lap welds on bodywork. Takes about a week to dry nicely. Happy with the result.

    This sealer is advertised as paintable. Perhaps I didn't read the directions carefully enough, but Tremclad rust paint turns the sealer into a gooey mess that remains sticky.
    Other than that, the sealer works great.

    5.0 out of 5 stars Good stuff!
    Reviewed in the United States on April 7, 2025

    I used this product to seal in new floor pans i riveted in an old Ford pickup I’ve been working on. You apply just like caulk, with a caulk gun. Cut the tip off as wide as you need the bead. This stuff sets up like hard rubber and I seriously doubt my seams will leak. I also used it in a couple of spots to hold down a dash cover on the same truck. If you are careful and wear rubber gloves you are able to use it without it being over messy. Otherwise it adheres to whatever it touches and very hard to get off your hands. I scrubbed mine and had to wait the better part of a week for it to wear off by itself when I used it once without gloves so keep that in mind. Otherwise, great product.

    We had a few cracks in the body panel of a sprinter van. After applying Bondo to the exterior and sanding it down, we used this seam sealer on the interior to make sure it was a water tight fit and protect the raw edges. It applies on like silicone caulk, and we smoothed it over with a flat spatula, which dried into a durable coat. So far it seems to stick on well without any cracking.

    5.0 out of 5 stars Great Product, Smooths out well
    Reviewed in the United States on February 20, 2025
    Verified Purchase
    This is a great seam sealer. Applies easily and smooths out well with a gloved finger. Flows out after smoothing to a smooth finish yet does not sag on vertical surfaces. Be nice if it came with an extra nozzel but you can seal it up with tape between uses and it's pretty easy to clear the "plug" of dried sealer from the end of the nozzle.
