Give me a great review on this product. HH-66 Vinyl Cement 8 oz The HH-66 Vinyl Cement 8 oz is one of those products that earns its reputation the hard way — by consistently working when cheaper glues fail. If you need a strong, flexible bond for vinyl repairs, this cement delivers professional-level results without the hassle. What makes HH-66 stand out is its incredible holding power. Whether repairing torn boat seats, inflatable gear, tarps, awnings, pool liners, truck covers, or outdoor furniture, it creates a tough waterproof bond that holds up against heat, cold, moisture, and heavy use. Unlike many adhesives that become brittle over time, HH-66 stays flexible, which is critical for vinyl materials that bend and stretch. The application is straightforward, and the cement grabs quickly without requiring complicated tools. Small repairs can often be completed in minutes, and once cured, the repair feels solid and durable. Many users also appreciate that it works well for both patching and seam sealing. Another big advantage is reliability outdoors. Rain, sunlight, humidity, and temperature swings don’t easily break down the bond, making it a favorite for marine, automotive, and recreational repairs. A little goes a long way too, so the 8 oz can lasts longer than expected for most household or hobby projects. Pros: Extremely strong vinyl-to-vinyl bond Waterproof and weather resistant Flexible after curing Excellent for marine and outdoor repairs Fast tack and easy application Trusted by professionals and DIY users alike Things to know: Strong fumes mean good ventilation is important Works best when surfaces are properly cleaned beforehand Dries quickly, so precision helps during application Overall, HH-66 Vinyl Cement 8 oz is a top-tier adhesive for anyone serious about repairing or bonding vinyl materials. It saves money on replacements and provides repairs that actually last. For DIY projects, marine use, or emergency fixes, it’s hard to beat.

Used to fix SUP patches & is working so far. Application is a bit messy with included lid-brush.
I used this to fix the D-ring pads and "daisy chain" attachment to my Tahé SupYak as well as reinforce the seams and hopefully extend the life of the inflatable paddleboard. Ease of application was ok, although a little bit messy with the brush attached to the lid that did tend to shed a little. It seemed to sorta blob on thickly and was a bit tedious as I ended up having to smear it around with my fingers because the brush quality wasn't great and just made more of a mess. It also does dry pretty quickly, but that's a good thing as it needs to dry enough to be tacky on both sides you're gluing belt sticking them together for the tightest grip. The 8 ounce jar was plenty for what I needed, even glopping it on so thickly and I still have some left in the event I need to fix or secure a couple more spots. It seems to be pretty durable so far, I've only used it a couple of times since gluing it, but it's all holding up well so far. I will see if it stands the test of time. I have hopes that it will. In all, I'm happy with this purchase so far, and would recommend it to a friend for family member. In fact, I have. The one star was removed for the brush shedding and the application being a bit more messy and thicker than necessary. Perhaps a separate brush not as thick and not stored in the lid would be easier. In order for one to get that now, he/she might have to buy a paintbrush separately to get to spots that are harder to reach than the thick nubby brush that is included can reach and fit between.
