Gasket cement?

[cus]

G'day Everyone,
Just on the silicone thing, use neautral cure silicone, without the acid. I think its been mentioned before by Brian.
I've been using it for years on exhaust headers & sometimes on one side of the gasket on the primary case, sticks
like s__t to a blanket! Usually comes under roof & gutter silicone (neautral cure).

regards, Cus

A quick question for Lannis who was kind enough to post a suggestion that Copper-Cote sealer works well for sealing a solid copper head gasket.

Now I've searched pretty hard for Copper-Cote and keep coming up with roofing or anti-fouling products. I did find a Copper Coat gasket cement (CRC 401516 Copper-Coat Liquid at:
    http://hires.amazonwebstore.com/CRC-401516-CopperCoat-Liquid-with-Dauber/M/B000M8Q194.htm

but that doesn't look right as it seems to be designed for paper gaskets. Can you possibly point me at a supply source (preferably UK based) for the Copper-Cote that you use please?

Many thanks,
John

G'day John,
                  this is the one I use http://www.permatex.com/products/automotive/automotive_gasketing/gasket_sealants/auto_Permatex_Copper_Spray-A-Gasket_Hi-Temp_Adhesive_Sealant.htm  or  http://cgi.ebay.co.uk/VHT-COPPER-GASKET-CEMENT-/110547417867?pt=UK_CarsParts_Vehicles_CarParts_SM  both work well on my 10.5 : 1 cafe.
Cheers

What Lannis is referring to is copper anti sieze grease.
You can get it from almost any good hardwear shop or nut & bolt shop or engineering supply store.
Three grades of anti-sieze commonly in stock are copper (normal use) Nickel ( extreamly high temperature ) and tefflon ( food  processing)

It is the came stuff that you should rub on your plugs before fitting them as well.
Take your big wallet in with you it ain't cheap but go for the big jar.
They try & flog you a 1 oz jar ( about the size of lip gel ) at 10 times the price per oz as the big jar.

clear bathroom sealant is good round the exhaust pipe /head junction

I think what your talking about is what t we call copper slip in UK, not outrageously expensive here ( and you don't need a lot per job )
Never thought about using it on a head gasket, a good idea though - nice one

Thanks Guys.

It sounds like the grease that gets used on brake assembly.

I really appreciate the fast and very pointed replies .... and I'm off to the local motor factors in the morning!

ll the best,
John

Hi, been on vacation and just now saw the post.

I'll have to look when I get home.  The stuff I'm talking about comes in an aerosol spray can, is NOT grease or anti-seize, and is very sticky stuff once it's sprayed onto the copper .....
