both surfaces air dry until the adhesive is tacky but will not stick to fingers.
NOTE
An initial supply of adhesive is supplied as item 3,
Section II, Expendable Supplies and Material List. (See
Appendix E.)
(4) Starting with an end, carefully attach the gasket to the metal. Press
into firm contact all over.
