I have a 60 year old Ferguson TVO tractor engine. The head and block have been skimmed to the limit. There remained some feint corrosion damage on the block that meant coolant could seep in to the cam follower chest when pressure tested.
Thus I fitted another new copper head gasket that I sprayed this product on. There is a slight difference in the way it was fitted in that I lubricated the head studs lightly this time so maybe the clamping load has increased slightly. However the treated gasket does not leak. I had the sump off whilst testing so I can be certain.
Make sure you degrease the gasket before spraying it. I ended up with some spots where it would not adhere. I had to clean it all off and start again.
I have yet to run the engine and will report back sometime. So in summary, I think this is potentially a useful product and seems to be a good buy if it works in actual service.
