I like blue Hylomar. I used to use some very runny brown sealant that set quite hard, does anyone remember what it was/is called? And any stuff for sealing head gaskets?

You should only need a light smear of oil for the head gasket.

Remember it may have to come off in the future Shocked

The modern equivalent is Red Hermatite but there were loads of similar stuff as used by gas installers most contained red oxide and red lead.

I still have ½ left a pint tin of my Dad's which must be at least 50 years old called Plasticote - this is supposed to be non-setting but it does eventually.

I use grease mainly on both cork, steel and paper. Oli on Corgasyl steel types wich are pre-coated

G,day Nick that brown /red stuff sounds very much like "Stag" to me and when I was a apprentice we always used grease on head gaskets and sliver frost paint on the rest

I was told years ago that Blue Hylomar was the only sealant approved by Rolls Royce. I can't vouch for the truth of that, but it is good and the one I use for preference.

Blue Hylomar is used in the aircraft industry and is on a recomended list for Rolls Royce.

I'd go for Blue Hylomar in most cases.

I think the Blue hylomar is very good. Where there is a machined face to machined face as on my Lotus I have been using what they recomended from 1985. Its called "wellseal" My god its sticky but like the Blue Hylomar its non setting so you can alway disassemble. I think its Rolls Royce approved too. Smells evry disticitve.
