MG TD TF 1500 - paper gaskets

I just received some gaskets from Moss for the retoration projects on my MGTD and TR6. Normally I just place the gasket between the 2 components and tighten down. The gaskets I got from Moss are paper thin and not the material you use when working on american cars. here is my question --- should I use a gasket sealer as well as the gasket when assembling? If that is suggested what sealer is recommended. I always find the responses extremely helpful.
Thanks Russ

When I rebuilt the TD, I got such a gasket for the rear axle. I thought they had to be kidding, I installed it dry knowing it would leak like a screen door. It didn't,not a drop. Last year same story with the TF. Id try it dry.

Depends on the where the gasket it going. some of the gaskets in our cars are very thin. others not. Where was yours going?

The one in real concern is between the pully housing and water pump (TR6) -- that one is thin as a sheet of paper and assuming water pressure, etc. I was concerned. I am just used to the stiffer composition of material and the thin paper composition threw me off.

Make sure the thinner the gasket, the cleaner the surfaces....

Most of the T-series sealing surfaces tend to be really rough, beat up, distorted, etc. even after cleaning up. My long time machinist/parts store owner friend got me using Permatex Aviation sealant on the paper gaskets years ago, with great success. I think it soaks into the paper as well. If the mating surfaces were perfect, you may not need anything. George

I have had success with the 3M yellow gasket sealer (AKA "Gorilla Snot")...It is just thick enough to seal the small surface irregularities...You can make minor adjustments to the gasket, before it sets up.

Contact cement. 3M yellow as above, on one side, grease on the other side. It will need to be taken apart again at some time, the grease will allow the gasket to be reused.

For thin gaskets, I have always use Shellack. This is an old automotive trick taught to me by my uncle 50 years ago. Shellack is impervious to oil and gas. You will lose the gasket if you need totake it apart but it will seal.
