Use this on your subaru
This is a good product to use on subaru head gaskets. Helps with over all sealing, just follow instructions and be sure to give it time to flash off before assembly

Must have for Gasket Work
Don't overthink it--if you're doing a gasket job and you're not a pro its going to take a bunch of time and effort. Buy this stuff so you only have to do it once. I replaced a head gasket with one off Amazon and it blew again a couple weeks later. Read a lot on forums on what do the "old pro" mechanics use and they kept mentioning this stuff. Re-did the job with this stuff and its holding up. Ended up using it for some other work too and I'm happy with it.

It seems to work
I had a gasoline leak in my boat fuel tank at the fuel sensing unit despite being new with a new gasket. Gasoline fumes in a boat can be deadly, so I bought the fuel specific Permatex to resolve that issue. I was surprised to see how liquid this gasket sealant was, I was expecting more of a caulk like substance like the other Permatex gasket sealant I used in the past. I followed the instructions and thoroughly cleaned both the tank surface and the underneath of the sensing unit, let it dry a few minutes and re-installed the sensing unit. It seems to work, the strong gasoline smell is gone, the real test will be taking the boat out and see how the repair holds up when the waves move the boat aroud. Will do a follow up after wards.

Good goo.
Well it stopped my ultralight aircraft from dumping 80 litres of fuel onto the hanger floor, so I guess it's doing it's job.

Bestes Produkt zum Abdichten von Benzin zu Metall
Es gibt nur sehr wenige Produkte die erfolgreich Vergaser, Ansaugspinnen, etc... abdichten da immer Benzin im Spiel ist. Normales Silikon ( auch Hochtemperatur ) ist nicht für Benzin geeignet. Dieses Produkt ist der Hammer, selbst verwendet und hoch zufrieden. Gilt für die meisten Permatex Silikone.
