I've used this product multiple times already. Primary use was used in conjunction with 'valve cover gasket' replacement, so far no oil leaking into spark plug wells.

Used it as a rubber sealant for frayed electrical insulators, repaired a broken rubber piece on my motorcycle's clutch shifter via c-clamp and RTV.

The cap on this product split in half...i just used the same stuff and glued it back together lol!

This stuff is 'man' version of rubber cement.

I use this stuff daily it seems (not really, but pretty often) as a mechanic. We get it in the 13oz tube for use in a caulk gun. The other type of RTV just doesn't compare. I'm talking about the vinegar smelling stuff, this is different. It adheres much better to surfaces than standard rtv, and as it states has better oil resistance. I have used it as the only gasket on transmission pans, differential covers, etc. I clean the surfaces up very well with brake clean and oil free rag, and put a small bead all the way around the surface, following the inside surface of the bolt holes. I've never had one leak using it, I won't go back to the regular stuff. Gasket kits from fel-pro often come with black rtv, that gets tossed and this used in it's place, I use it in addition to water pump gaskets, o-ring sealing surfaces, well lets just say anything that would benefit from rtv.

I've only not used this stuff on water pump gaskets twice, and I've only had a water pump gasket leak twice. I'm going to continue using it. Some say not to because they find it hard to clean off. Well I'll tell you that this is 100x easier to clean off than those really old and been on there a really long time gaskets that were applied dry. Plus this stuff pretty much deteriorates after any decent exposure to brake clean, so spray it, wait a few minutes, and it will be soft. (This won't effect it's use as a gasket, it only gets the outer areas wet)

I love this stuff. I've used it on 2 cylinder heads and after thousands of miles they're both leak free.

This RTV is intended for primary use as engine gasket maker - temperature and oil resistant. But it also works well as general purpose RTV when the near-black (dark gray) color is desirable. Which was true for my application - making gaskets for mounting car speakers in odd sized door application that required custom spacers. Worked great.

The dark color is especially troublesome to get off the hands - use disposable gloves during application.

This package, a small "squeeze" tube is not easiest for application of a regular bead. It is easier to use the slightly larger, calk-gun sized package, so consider that if the larger quantity is also helpful.

Permatex Ultra Black is the RIGHT STUFF for sealing or making gaskets for engines, transmissions, transfer cases, differentials, or anyplace where maximum resistance to conventional or synthetic oils is absolutely necessary.
It resists all sorts of chemicals and oil additives, such as those used in limited-slip differentials, automatic transmissions, and racing lubricants.
I threw away all the other gasket sealers, and use the UltraBlack for just about every job that comes into the shop.
When a leak means a do-over, I don't take chances -- UltraBlack seals it RIGHT the first time ! !

I have used this as a primary gasket maker for rear differential pans, transmission fluid pans, oil plug thread sealant/leak-proofing, motorcycle engine case gasketing and other uses. It also works well as a gasket dressing. Apply a thin film on the pan itself, then the gasket, and then apply a thin film of this stuff over the gasket, then bolt it down, but only a lightly snug. Let it firm up for an hour or so and then torque to spec. Allow a full 24 hours for product to cure before you fill with fluids and drive the vehicle. This stuff works very well. It's the best Permatex makes. I wouldn't mess around with the orange or blue stuff. This is the best.

Used this stuff for years! Great automotive gasket maker and adhesive - I probably use it more as an adhesive than making gaskets - Works either way - I consider it Permatex's Best Product - Never w/o it! It will harden up in the tube once opened so have plenty around in fresh unopened tubes for when U must have it!!! ~:0)

This stuff has a ton of uses around the home and garage.

The ULTRA BLACK can be layered and feathered very thin, so you can use it as glue in some cases where you need a "flexible" glue. For example, I use it to repair punctured or torn HiFi Speakers or surrounds. It also makes a great glue for re-attaching auto parts like rubber door moldings. Of course, you can use it as a gasket sealer.
