### ⭐⭐⭐⭐⭐ A Game-Changer for DIYers!
*by A***S on June 26, 2025*

I'm seriously blown away by the Permatex 25228 The Right Stuff 90 Minute Black Gasket Maker. It's like a magic potion for fixing things! 🪄 The ease of use is off the charts - it's a total game-changer for any DIY project. The best part? It sets in just 90 minutes, so you can get back to business in no time.🕒 The 3 oz tube is more than enough for most jobs, making it super cost-effective. I've used it on multiple projects and it has never let me down. The only downside is that it's a bit messy to work with, but hey, that's the price you pay for such a fantastic product! I highly recommend it to anyone who loves fixing things around the house. 🔧🏡

### ⭐⭐⭐⭐⭐ The right stuff is the best stuff
*by B***H on June 5, 2025*

this is my favorite gasket sealer. been working on cars since the 80s, and watched as gasket sealers evolved. back then you had 2 choices, forma-gasket #1 (dries hard) or forma-gasket #2 (non drying paste). now there are so many types it can be confusing, but right stuff is exactly that, the right stuff. Works sealing cork and paper gaskets, holding rubber or silicone gaskets in place, or even laying a thick bead to “form a gasket” acting as an adhesive and a sealant. best example i can give is the intake manifold gaskets on the original small block chevy, (not the LS motor of today) it had a rubber gasket at each end that were notorious for blowing out due to excess crank case pressure. throw those gaskets away, lay a ¼ inch tall bead of this across the front and back of the block where the intake sits, set the intake down on it, wipe away the excess that squishes out, and it’s sealed for life. get it on your hands? let it dry and it peels right off

### ⭐⭐⭐⭐⭐ Convenient and Reliable Valve Cover Gasket Maker
*by Y***Y on July 14, 2025*

This product offers convenience by eliminating the hassle of squeezing it out of a tube. While it may be slightly pricier, the user-friendly application and leak-free seal it provides make it worth the investment. It stands out as the best valve cover gasket maker I've used, delivering on its promise of durability and high water resistance. Trustworthy and easy to use, this product offers exceptional results and peace of mind for those seeking a reliable gasket maker.
