RESULTS OF Fo8 SEALANT THREAD=E2=80=94Thanks again to all who =
contributed
We had around 25 responses of one sort or another, several good =
suggestions and a couple of =E2=80=9Cheads up=E2=80=9D regarding =
=E2=80=9Caggressive=E2=80=9D motor oil potential reaction with some =
sealants.
Most popular with 7 users was HYLOMAR BLUE
Next was PERMATEX AVIATION with 5 users
Then came YAMABOND #5 with 3 users
Followed by unspecified SILICONE with 2 users
COPPER COAT, PERMATEX BROWN and INDIAN HEAD SHELLAC each had 1 user
Several responders suggested that perhaps if the mating surfaces (see =
below) were in good shape then no sealant al all might be the way to =
go...
One responder (with a couple of like minded individuals)suggested using =
an old liner cleaned up and true as a sort of hone to polish the =
=E2=80=9Cland=E2=80=9D in the block. This might also work to emphasize =
highs and lows in the land if a bit of Prussian blue was applied to the =
land prior to using the =E2=80=9Chone=E2=80=9D.
