Best Sealer Against Old Paper Gaskets

[Deleted Member 4613]

The Permashield I chose is resistant to all fuels and ethanol,
and is good to 500 degrees F. But expensive. It's called orange
Permashield, available at Autozone. Useful as a dressing on
paper gaskets.

I wrote to Permatex and they said Permashield would work
and also Aviation A 3# would also work. I like it because
I can order a small 4oz can for $11 from O'Reillys.

I'm not sure it is alcohol resistant even though Permatex recommended it.
Read more about this product and it is not recommended for
ethanol containing fuel. I'll go with Permashield.

Good work.

And note, non of the engines I've worked have blown out the sealant.

I've used this before... It's works great just a mess and it doesn't like to come off... All there was before RTV

Normally good stuff but not for ethanol/fuel.

I've been a licensed automotive tech for 30 years, in my experience ultra grey works really really well. Ultra black works well also. The Right Stuff is also really good.

I love "The Right Stuff". Been using it for decades now. It's basically Hondabond without the price tag. I get it from WorldPac, 2 bottles with caulking gun. Otherwise I just use a tiny ball peen hammer and gasket material. The round end of the hammer banged against the object you are trying to gasket makes quick work of custom gaskets.

Reminds me of this

Gasket Making 101

Howzit Everyone, $SAVE MONEY$ Gaskets made easy. Don't reach for the razor blade. Grab your 8oz alignment tool (ball peen hammer) and tap it out, Lightly tap gasket around the edges. As you tap out the bolt holes put bolts in to help keep gasket aligned. The 1/32" rubber fiber sheet is great for...

Leather punch set and exacto... An alignment drift would get into smaller pieces... A cotter pin extractor is really good for cardboard gaskets... I don't pull cotter pins with it... I'll cut those when the nut comes off

Old Skool hole punch
Use empty bullet shells as hole punch .22. .45 etc...
