Review: great permatex - had before works great to hold gaskets in place
Review: Used on a Rear Differential Gasket, No Leaks - My axle seals in my 1993 F-150 failed and leaked over my brakes, so a repair was needed. That meant draining the rear differential in order to gain access to the axle. There are many schools of thought regarding how best to re-attach the cover to the differential once the work is done. Options include: RTV only, gasket only, gasket with RTV and gasket with this high tack sealant. It seems the preference has moved to using RTV only especially in newer vehicles. That may be related to manufacturing processes and the simplicity of having an automated tool dispense the RTV as the axle moves down the line. Keep in mind that the differential is likely facing upwards during the manufacturing process to facilitate the RTV application. In the real, shade tree mechanic world, this rarely happens. The surface is vertical and presents minimal challenges, but one can still mess it up if not careful. I’ve used RTV only in my 2014 F-150 and have evidence of minor seepage. That’s on me, as it was the first time that I ever used RTV only, as that was the OEM process. In contrast, my 1993 had a gasket and likely an adhesive. It was a bear to clean, as I had to scrape its remnants from both surfaces. I replaced the fluid in 2018 and used a gasket and RTV. Reading further into the best practices, some folks commented that a gasket and RTV should never be used together. I wish I read that earlier, as there was evidence of minor seepage beyond the gasket. I then took a deep dive into the F-150 forums and found someone who had suggested using a gasket with Permatex High Tack Gasket Sealant. He noted the sealant doesn’t harden or cure, so re-servicing is slightly easier. I opted to give this a try, and I’m glad I did. I made sure both surfaces were free of gasket, grease, dirt and RTV. A light sanding on each surface was followed by a wipe with brake cleaner. Make sure the sump in the bottom of the differential is empty, or at least not near the edge, as it may wick over and drip on the bottom surface and render your seal useless. As I noted above, there are multiple suggestions as how to apply this to the surfaces and gasket. Here’s what I did. I laid the cover flat and applied the sealant to the sealing surface. The sealant has a brush. I ensured there was a good coating especially where the gasket would be in contact with the cover. I then applied the gasket to the cover. The sealant holds the gasket in place, so make sure you align the holes. This sealant is unique in that it gets stringy when exposed to air. I found it best to work quickly and not to go over areas multiple times to avoid clumps. I then applied the sealant to the other side of the gasket, that is the side that’s against the differential surface. It was just easier for me this way, as I was working on the ground. You can likely add it to the differential if you’re working with a lift. Excess towards the inside of the cover, and therefore differential, can be wiped after the gasket is laid on the cover. I carefully aligned the cover, added 1-2 bolts to hold it in place and then torqued all 10 bolts to 30 ft lbs. I don’t think there is any cure time with this product, but seeing as I had other things to do, I left the differential empty until it was my last task. That was about 1-2 hours later. There are no leaks, so this will be my preferred method going forward with this truck. Good stuff.

## Questions & Answers

**Q: The big question is what is it like removing this stuff when things have to come apart again.**
A: no problems there are a variety of chemicals that will remove this sealer quickly and quite easily brake parts cleaner naphta acetone to name a few mechanics will tell you which I am that you usually only have to use the sealer on one side of the gasket which will hold it to the part so for instance EX>. a thermostat housing will have the gasket sealer on the housing side so that when you unbolt it the housing comes off with the gasket attached to it and the intake manifold is still clean, but there are some instances where both sides would need sealer like you made the mistake of putting radiator stop leak in and now every part of your cooling system is clogged and the water can't circulate making the pressure build up & up till something lets go usually this will be the gaskets>>EX. thermostat, intake manifold, water pump so that's a little tip for you and here's another one if you did put some sealer into the radiator it must be cleaned out and the use of (a)cascade dishwasher powder will help (b)white vinegar and salt  will take out the sealer plus any calcium deposits and rust from the complete engine cooling passages====== if this has happened use the vinegar mix first then the cascade then fresh with the baking soda to neutralize the acid content then fresh water again to clean it out altogether followed by fresh antifreeze and distilled water never add house water to your radiator or battery the calcium builds up in radiators very quickly and the impurity's kill the battery acid plates with the same build up that's just a few tips for you as a bonus O.K.

**Q: Is this suitable for use on an oil filter housing gasket? the gasket lies between two cast aluminum pieces with up to 80psi of oil pressure.**
A: 80psi is pretty light pressure when it comes to engines and oil doesn’t get very hot unless there are extreme problems... almost any gasket sealer should work well. Most of these sealers are made strong enough to hold and seal the head gaskets which is many folds more pressure than any of the internal fluids.

**Q: is this good when replacing radiator hoses?**
A: No, I only use this product for gaskets.  When replacing radiator hoses make sure the mating surface of the hose is clean and not pitted.  Next apply a very light coat of a heavy grease (Grease used in a grease gun or grease used for wheel bearings.) to the surface.  Next wipe the grease off of the mating surface with a dry cloth or paper towel.  This will leave a very thin almost non-existant film of grease on the surface.  Slide the hose into position and clamp.

**Q: This 80062 spread on gasket sealer for cork should it be put on transmission pan and gasket like contact cement ?  Should i both sides of gasket?**
A: I always use it on one item to more or less glue cork gasket in place. I would put it on pan then place gasket. Then you can assemble without gasket moving.
