Review: The GOOD stuff! - The good stuff - can't say the "great Stuff"- another brand has already calmed that name, but it is great. Easy to use, never dries in the tube ( in fact it never completely dries ever). Seals gaskets good, but they can can be removed when necessary with out a chisel and hammer! Resistant to most automotive chemicals. I have used this for years on everything from lawnmowers to hot rods. Do it rite the first time, and you don't to worry about globs of silicon coming loose inside the engine or whatever. NOTE: this a sealer / conditioner for gaskets on correct fitting parts. It is not designed to glue things together or make up for damaged or ill fitting parts, or as a substitute for a gasket. Other brands have in the past claimed the the term Hylomar, but they are not the real deal.

## Questions & Answers

**Q: gasket marker or gasket maker?**
A: Neither marker or maker.
It is a joint sealant that can be used with or without a gasket

**Q: Can I use this to permanently seal the  24" X 24"inspection  lid on my boats onboard 60 gallon gas tank ?**
A: If you are using a gasket, I would guess Hylomar would be a good product. I did use this product on a rubberized cork gasket for a fuel sending unit. Hylormar did the trick nicely. 
If you are not using a gasket, I don't think Hylomar would be the right product. Hylomar doesn't dry out or cure as a permanent gasket maker like RTV sealant.

**Q: Has anyone used this on a BMW valve cover gasket with good success?**
A: Hello!  I have used this Hylomar gasket to seal MG head gaskets, Cadillac 4100cc intake manifold gaskets, and other really difficult applications.  I can't see that a BMW valve cover gasket will pose any problems.  Just apply a thin film on both sides of the gasket and close within 10 minutes.  The Hylomar never dries out so it doesn't shrink.  The secret to valve cover gaskets cork or rubber is to not over tighten the retaining bolts.  There is probably an Inch Pound torque spec for your car which you should follow.   Hope this helps.

**Q: Can this be used on diesel injector threads?**
A: I would say yes

### ⭐⭐⭐⭐⭐ This is great stuff for certain jobs.
*by J***M on January 20, 2025*

Originally used this stuff as an aerospace overhaul mechanic when it was made by Rolls-Royce. Had a tube around for about 20 years and finally used it up. Unlike silicone it won't set up in the tube so it's great to have around and keeps. It never hardens and I've used it on multiple low pressure seals that have been leak problems for me. Unlike silicone sealers, if you need to disassemble something you don't have to spend a bunch of time cleaning out the old silicone before reassembly. Also good for keeping gaskets in place during assembly - the hylomar website has good guidance on uses. The one thing to know is that it can be messy if you're not careful- it can tend to get all over things. It's water, gasoline, etc. proof so clean-up can be a problem. I've found that 91% isopropyl alcohol does a great job of removing it, though - much easier than messing with old set-up silicone.
