Hondabond vs. Permatex: what’s the difference?
In my experience, Hondabond takes the checkered flag over Permatex when it comes to gasket makers. Hondabond had better seals and stick-to-it-iveness. Permatex did a middling job on both fronts. When I need to get the job done right, Hondabond is still king of the garage.

ā Pros: Hondabond for Oil Pan
First and foremost, it’s important to note that Honda Bond is specifically designed for use on Honda vehicles. So if you own a Honda, you’re in luck.
Do I Have to Use Hondabond On My Oil Pan?
Hondabond worked great for making a seal when I replaced my exhaust resonator. It can get messy, though. It’s sticky and sticks to your fingers and clothes. It’s a bit tricky to remove. I suggest cutting the tub off and squeezing it as hard as you can.
Incredibly Effective
Honda Bond has been incredibly effective despite its initial messiness. My exhaust system has been sealed for a month now. I’m not sure if this is its intended use, but it worked great.
Useful Technique
Squeezing the goo out of the tube can be a bit tricky if you don’t work with your hands every day. However, I found a useful trick. Roll the bottom of the tube to create pressure, especially if you’re dealing with a small hole. It’ll make the application process a lot easier.
Sealing the Valve Cover Gasket
Apart from my exhaust system, I also used Honda Bond to seal replacement parts on my vehicle that were no longer exact fits due to rust and wear and tear. It did the job perfectly. In fact, Honda themselves recommended Hondabond for sealing the valve cover gasket 
on my ’14 Accord during a replacement.
Can You Use Hondabond With a Rubber Gasket?
It’s specifically designed to seal metal-to-metal connections under the rubber gasket that may leak oil. I followed the instructions, applied the Honda Bond, and waited the recommended time before adding oil. It has been 2000 miles now, and I haven’t encountered any leaks.
OEM Recommendation
I know there are other alternatives out there, such as Permatex silicone sealer
, but why take the risk? When it comes to sealing and bonding, I believe in going with the OEM (Original Equipment Manufacturer) recommendation. Honda Bond has proved its worth time and time again, and I wouldn’t settle for anything less.
In terms of usability, Honda Bond is a breeze. It’s easy to work with and holds up exceptionally well, regardless of the application. The folks at Honda really know how to create products that deliver outstanding performance.
āCons: Hondabond
Now, I must admit that working with Honda Bond can be a little challenging due to its tacky nature. It tends to stick to everything it comes into contact with, which can make spreading it a bit of a hardship. However, the seal it creates is well worth the effort and inconvenience. Just be prepared for the stickiness.
FAQ of Hondabond High-Temp Silicone Liquid Gasket
Q: Can I utilize Hondabond to seal the cam seal on my Integra?
A: This sealant is of exceptional quality and primarily used for motorcycles. It should effectively seal your cam cover without any issues.
Q: According to the 2008 Honda Civic service manual, it recommends applying “liquid gasket” to the engine block coolant drain plug before installation. Is this applicable?
A: This is the finest liquid gasket sealant I’ve come across for Honda engines. It works exactly as advertised if you follow the instructions.
Q: I have a hairline crack on the inside thread of where the oil-sending unit screws into the block of my car’s engine. Will Honda Bond stop the oil leak?
A: When applied correctly, Honda Bond serves as a reliable sealant and gasket maker. While I can’t guarantee it will fix your issue, it’s worth a try at just $12. Apply some sealant on the threads of the sending unit, reinsert it, and ensure proper drying by following the instructions. Worst case scenario, you’ll be in the same situation, but at least you gave it a shot. It won’t cause any harm.
Q: Can I use Hondabond for a head gasket on a model airplane motor that uses glow fuel?
A: In the past, we used aluminum spray paint for head gaskets, and there are copper-based sealers available as well.
Q: Is Hondabond the right product for the clutch cover? I need to replace the gasket on my 2007 CBR600RR.
A: Hondabond 4 appears to be the more popular choice. However, please note that the 2007+ CBR600RR does not require a gasket for the clutch cover.
Q: I purchased Hondabond for the oil pan seal on my Accord. Can I fill it up with oil and drive after 1-2 hours?
A: No, I wouldn’t recommend it. You must wait at least a day, but ideally 2-3 days before filling the oil pan with oil.
Q: What color is the bond?
A: The bond is gray in color.
Q: Can Hondabond be applied in cold weather, around 30 degrees Fahrenheit?
A: I applied it at approximately 40 degrees, and it has held up for one year.
Q: Will Hondabond help seal the vacuum leak between the carb and the engine on my Husqvarna chainsaw?
A: You’ll need to completely remove the carb, thoroughly clean all surfaces, and then reseal it as instructed on the bottle. While it should work well, if possible, it would be faster and likely better to obtain a factory gasket. Unless the mating surfaces are damaged and you need the liquid sealant to fill in flaws, or if you can’t find a cut gasket and regular sealant.
Q: How many tubes do I need for the oil pan?
A: You only need one tube, and you’ll only use a portion of it. I used it on a 1991 Honda Civic oil pan, applying some in the four corners as mentioned in the shop manual.
Q: Can I use Hondabond to seal a leaky rubber gasket on an air conditioner? The condensation from the AC is leaking into the electrical compartment.
A: This gasket material is designed to compress between two objects, so if you’re using it solely for an outer seal, it may not hold.
Q: Is it suitable for sealing the chainsaw head?
A: I’m quite certain it will work.
Q: I have a 2001 Acura Integra GSR and need to replace my fuel pump and oil pan gasket. Is this the right sealant to use?
A: It’s best to consult your auto manufacturer. Most cars come with a kit that includes a transmission filter and oil pan gasket, unless the manufacturer uses liquid gasket in place of a rubber gasket.
Q: How long does hondabond take to dry before I can add new oil to my 2004 Accord V6 engine?
A: It can take between 20 minutes and up to 2 hours. The best approach is to apply a small portion of the sealant, similar to what you’re dealing with, on a disposable piece of paper or any suitable material. Check the sealant every 15-30 minutes. If it has hardened and no longer sticks to your fingers, it has started to cure on your engine and is safe to beexposed to oil or coolant.
Q: Will Hondabond work between the cylinder and crankcase of a chainsaw?
A: Hondabond is specifically designed for cases and covers, not for the cylinder area.
Q: Would Hondabond be effective for sealing water pump mounting bolts to prevent coolant leaks?
A: Personally, I prefer using Honda Bond HT over the regular Honda Bond because it is thicker and easier to apply. It provides excellent sealing for motorcycle engine side cases and cylinder heads, so it should work great for your water pump as long as it’s not warped. I’ve used Hondabond extensively and it surpasses anything else I’ve tried. I have worked on numerous motorcycles and ATVs.
Q: Hondabond showed up when I was searching for a valve cover gasket. Should I use it with a gasket or instead of it?
A: No, Hondabond is not a replacement for a valve cover gasket. If your model requires a valve cover gasket, you should use the appropriate gasket.
Q: Is this the right Hondabond to seal my leaking Honda mower transmission after I open it?
A: I believe it should work on your mower as well. However, it’s always a good idea to double-check.

My Hands-on Test of Permatex Ultra Grey 82194
ā Pros: Hondabond Equivalent?
One particular use case that impressed me was its effectiveness in securely sealing the transmission case and cover on my tractor. No leaks, no issues whatsoever. It gets the job done, and it lasts a long time, which is essential when you’re dealing with heavy machinery.
Seal the Oil Crankcase Gasket On My Scooter
I first used Ultra Grey to seal the oil crankcase gasket on my scooter. I applied the sealant easily, and it cured perfectly, preventing leaks. This success inspired me to try it on my car’s valve cover gaskets. I applied a 1/8-1/4 bead of sealer all around the cover, waited 10-15 minutes, then installed it. Since then, the valve covers haven’t leaked.
I also have a problem with my rearview mirror falling off. After cleaning and lightly abrading both surfaces, I used high-temperature double-sided epoxy tape. Since months ago, the mirror has been securely mounted with a little support.
As for other applications, Ultra Grey seals water pump bolt threads like a champ. Sealant stays in place and doesn’t compromise the bolt.
Ultra Grey is unique in that it doesn’t have to cure before use, unlike other sealants. I used this to seal a Beans sump underneath a diesel tank, even with the surface wet. Over two years now, the seal still works.
In addition to sealing motor gaskets, Ultra Grey could also seal inspection hatches or top plates on diesel tanks if they’re thoroughly cleaned first.
āCons
I’d use Ultra Grey with caution when sealing wood stove chimney pipes or range hood ducts. You’d probably be better off with products designed for those applications.

Should I use some of Hondabond on my oil pressure sensor for my 2017 CBR1000RR? It has a very small leak, a few drops a day.
If the oil pressure sensor is leaking from the threads, you'll need thread sealer instead of silicone. If the sensor is leaking from the housing, it needs to be replaced. Silicone, Teflon, and other products are not recommended.
