    Didn't level as well as advertised. Had to smooth it out manually which defeated the purpose. Maybe I got a bad batch?

    Excellent adhesion. Used it on a tricky roof patch and it held up through heavy rain. Very impressed with the durability and ease of use. Definitely my go-to sealant now.

    It works okay. Had some issues with the nozzle clogging halfway through. Product itself is fine though.

    Been using Alpha Systems for years. This tube is consistent quality. Seals tight and stays flexible. Top notch.

    Perfect gray match for my vehicle. Self-leveling feature saves so much time. No sagging at all. Will buy again.

    Good product. Takes a bit longer to cure than expected but the finish is smooth and professional. Worth the wait.

    Love the low VOC formula. Smells way better than the old stuff I used. Works great on my trailer seams.
