Permatex82099 Spray Sealant, 12 oz.

First time using this. Hope that ir seals the area needed. Sprays on well. Tape off the area you do not what the over spray on.

Goof as advertised

not the best but not the worst way to hide leaks, if there is no high pressure in the system works great with both pistons and hydraulic fluid

I used this on a small oil pan leak from the seam. The car manufacturer used gasket maker but this stuff worked. Just make sure to prep with brake clean like the directions say then use a clean rag to wipe up the rest. Then apply 3 to 5 coats waiting at least 1 minute in-between coats. Trust me it works.

It’s ok , but still noticed drop .but very minimal

16 Month Update:Code never came back. This product sealed the vacuum leak - which had been plaguing me for years.*************For a long time I had been having an intermittent check engine code that relates to the evap emissions test part of the OBDII on my 2005 Mercedes C230. It does not affect the operation of the vehicle or the engine. It just means there is a small vacuum leak when the system tests itself which throws the code. Consequently you can’t get your car smogged or registered. I read in various places that this is a common problem with this vehicle and even watched YouTube videos of people addressing repairs etc. I learned thanks to all this information (!) that there is a specific spot close to and just behind where the fuel filler opening is located. The part includes a plastic barb which a hose connects to. The barb develops a hairline crack causing a “small evap leak” (P0456).Many people solved their issue by replacing the entire filler neck assembly, which can cost anywhere from $150 for a used part to $500 for a new part. Not to mention the 2-4 hours in labor.The vehicle has a rubber shroud directly behind the fuel inlet which you can push down with a flat screwdriver. You can see right in that location where the suspect part is located. I used the straw attachment and sprayed all over that area about 5-8 coats of this liquid Permatex. It sprays on like liquid and congeals into a nice rubber sealant after a few minutes.I have not had the P0456 code since using this spray sealant. Given the tight space limitations involved, there’s no way I could’ve made this repair using a different product.I would recommend this product for any low pressure (or vacuum) leaks. The straw sprayer is perfect so you can get into tight spaces. It seems particularly suited for things like what I accomplished - sealing a hose/barb fitting - a weak spot in any vacuum system.

If I could give this product, a lower star, I would give it negative stars. This product is a waste of money. All it makes is a gooey mess, and it claims to seal leaky fuel tanks. Well, that’s not true. Don’t waste your money.

So I had a leaky transmission pan that would go thru about a gallon of transmission fluid a year. I had to constantly check my transmission fluid level and when it was low my car would shift terribly. I've brought my car to two different mechanic shops and neither of them could totally fix the leak. I spent almost $1000 on them.I sprayed about 6 coats of this one day. It helped the leak but didn't stop it. I did the same again and it completely stopped the leak. Years and 5 mechanics later this was the only thing that worked for me. I used this a little over a year ago and it's still not leaking.
