Instant Gasket

I'd second the warnings about using too much. It will ooze into the inside of the cavity and then there's a risk of a blob detatching and causing mayhem inside the engine. If you're sealing two machined surfaces, you'd be amazed how little of the suff can be "too much"!

I know that it's old school, but we swear by chartpaper as a substitute gasket!

Many a cancelled chart used on ship as gasket, stencil etc.

But my cancelled charts are priceless and woe betide anyone who touches !!
 
For anyone who rode Lambrettas like I did, they know that one of the biggest problems was getting the chaincase to seal. Being a large alloy joint it used to warp so easy and the threads in the alloy would chew up. Having had a few Lambo's as a young'un - I must have used loads of Hermetite and corn-flake packets on them !!
 
many modern engines use instant gasket in lieu of paper or cork gaskets. To avoid any excess getting inside the engine I always apply the bead to the outside edge of the face to be sealed. That way the excess is squeezed outside the engine.
 
Instant gasket/silicon sealer is wonderful stuff but in the hands of an idiot is an expensive disaster waiting to happen, I have rebuilt many engines to find the cause of the problem is a string of rubbery mush in an oilway, even had it on aero engines, always use the thinnest layer you can get away with and clean up the excess.
