At the risk of starting a huge debate of whether or not to use gasket sealer with new gaskets, what have those of you done during your right shift conversion?

Purchased conversion kit from CMW and it did come with a gasket for the inner trans cover. Is it necessary, or recommended to use any type of permatex along with the new gasket? I've read conflicting reports. Some just indicate to smear with bearing grease? Others, say no to permatex...some say definitely.

Your thoughts and experience is appreciated!

 Don't know about anyone else but I used a very thin coating of silicone on both sides of my gasket and no leaks of gear oil so far.

I use sealer on everything. You just use the type that is easily removable.  ERC

Thanks. Any recommendations of type of sealers? I have some Permatex Ultra Black RTV, would that suffice? I know to only apply a thin coat to both sides.

I like the ultra black and ultra grey.  Both work very well.

Permatex Moto Seal. The dirt bike guys use this because they tear them apart all the time and seals well. Frankly I use Wellseal but it's hard to find. But doesn't harden you can pull  it apart again.   ERC

Thanks guys. Went with the Permatex Ultra Black, since that's what I had in shop. Hopefully, I won't be pulling it back apart any time soon!

Ultra Black cleans right up with a wire brush wheel on a drill.  ;)

IMO, using a wire brush on an aluminum part to clean off a RTV sealant sounds a bit extreme.  Most silicone sealants don't adhere to the metal surfaces with much grip and should peel/scrape off quite easily.

Ultra-Black and a lot of other modern sealants are oil resistant/proof and work fine.
To those who have a tube of bathtub/window/general purpose Silicone, a word of warning.

Many of these are not oil resistant and a lot of them produce acetic acid while they are curing.  Acetic acid, smells like vinegar and it will attack aluminum parts.
Don't use these to seal oily or aluminum joints.
They are OK for sealing areas containing water if the metal in the joint is cast iron or steel.
