Absolutely top quality RTV
Super heavy duty. I used it for several applications including a seal at the bottom of my big old fountain. Great material.

Came without the nozzle
Great product, however it came without the nozzle. I reordered and it came without the nozzle again but Amazon support took care of it perfectly.

Good stuff
No complaints. Worked as well as permatex and it was a bit more affordable. I'd also note that getting this stuff in a caulking tube is pretty much the best thing ever! So much easier to control than those stupid tubes!

Great Adhesion and Easy to Use
Purchased this product to do an oil pan replacement on my daughters 2007 Saturn Ion3. The factory oil pan doesn't come with a gasket. I utilized this as the gasket/seal between the engine and oil pan and it has held up well. I checked the oil pan after a few months and found that there were no leaks at all. After only using a small amount of the tube, I was able to utilize the tube again for another project. I was very surprised that it had not gone bad after months. Recommend following the directions on the tube when utilizing this product and you will be satisfied with the outcome.

Very impressed with product. Perfectly sealed my two valve rocker covers on my big V8 turbo instead of using gaskets. I made a sample dab the size of a bottle top and half inch high onto cardboard and let it set overnight and I was amazed how well it can compress without destruction and still return to its original dab size. Will definitely use this gasket maker again on my future engine repairs.
