Excellent compound terrible packaging.
4 stars for packaging woes... Pros: Sticks REALLY well, to any surface it seems. Hest resistance seems to perform as advertises. It is easily on par with automotive compounds in terms of gripping power and is highly resistant to a variety of common solvents... this is a double-edged sword because... Cons: Tube is not crimped at bottom, Nozzle fits loose, they dropped the ball hard on packaging. If you squeeze too hard while working with smaller bead sizes ( sub 5mm) you're probably going to get a whole bunch of the compound spilling out of both ends. Prep work is absolutely essential to getting the most out of this product. HVAC and Painters tape will be your best friend, if only for the fact that it is very difficult to scrape off once it has been cured. I have more than enough experience with food grade RTV compounds, but this particular one leaves little room for error.

Works and it’s easy to use. Sealed great.
Great product. Works well. Easy to apply. We sealed our openings on our bbq pit / smoker. After it dried and we took the tape off it’s completely sealed again. Great price to fix our pit rather than replace it.

Did it’s job
This stuff worked great to fill a small gap along the edge of my portable grill. Now there is no more grease running down the legs and on to the table. It was easy to apply and adhered to the stainless steel with no prep work involved. Let it set for 24 hours to cure and fired up the grill. According to the on board thermometer, we got it to just over 700 degrees and this stuff didn’t become soft or peel away. Just wish they sold a smaller tube as the standard tube was way to much product for what I needed it for.

Great product, hot garbage container.
Love love love lavalock RTV. works great, keeps all my smoker gaskets in place. hardly any off gassing and great adhesion if used properly. My complaint is the tube and tip combo this tuff comes in. Order it twice, first time the bottom splits open at the crimp and RTV comes pouring out while I'm trying to apply it. Fine I get it, stuff happens. Second tube for a new smoker. Tip fits so poorly on the tube that when you squeeze the RTV out tip unscrews, pouring RTV out the tip and the bottom of the tip that has just come unscrewed.
