Gasket & metal surface sealants
^^ that is the point it seals without setting I assume he knows thisPosted 4 years ago
Why are you putting a gasket where there is no gasket? do you mean there was none or you dont have any? Should one go there?
It works between metal to metal to answer your question and it never hardens so should be fine.andylMember

It doesnt set like silicone gasket sealants but i quite like that idea and I have heard good things.Posted 4 years agoTreksterSubscriber
What he says ^^^^^^
Water proofing the Landy? Served my “time” on the inc 2 factory courses and never used it on any of those parts.
Used to be a standard addition to any mechs tool box when I was a “boy” (40yrs ago!). Modern jointing materials tend not to need any additional help.Posted 4 years ago
In current job if a joint leaks it is either u/s or joint faces need remedial action, not used any gasket sealant for a long time.
Id just seen reference on a landy forum to applying a sealant to the clutch slave face when refitting. I need to get some sealant for use on some gaskets in the future, and was wondering if this stuff might also be used for metal/metal facing as well. But if peeps reckon it’s unnecessary then fair enough.Posted 4 years ago
I asked what vehicle as i thought you where going to use it between a concentric slave & a gearbox casing inside the bellhousing . It would not be suitable for that application .
I’m guesing people have used it on land rover slaves to prevent corrosion between the two surfaces ? I can think of no other reason , if this is the case , a thin layer of grease would be ample i’d have thought .
Personally i like to let a gasket do it’s job without any clag on it . If you do need to give a gasket some assistance then a good quality rtv sealer is what you want . rtv is what you ned for metal/meatal sealing . Avoid using rtv’s on oil feed pipes to turbo’s etc as it can easily block oil ways and galleries .Posted 4 years agocrikeyMember
It does work superbly as an alternative to carbon paste for fitting carbon seatposts to alloy frames, or alloy seatposts to carbon frames, or carbon seatposts to carbon frames.
It was recommended to me by someone from Trek USA after I had an alloy post get stuck in a carbon frame.Posted 4 years agooliverd1981Member
When is sealant used on gaskets like head or rocker cover?
When you can’t get it to seal and you’re a bit desperate.
We have a drive coupling on one of gas turbines that had a problematic oil leak until we reassembled it with a liberal coating of red Hylomar. I’d assemble if with light grease and see if there were any oil leaks before resorting to sealants.Posted 4 years ago
Cork gaskets are a bit crap and can benefit from a thin coating of sealer . DO NOT use sealer on head gaskets , just ensure head & block faces are clean of all traces of old gasket etc clean with brake cleaner to remove oil & grease then fit gasket dry & torque down head bolts in sequance .Posted 4 years ago
