Attention: Jim Hoey
Jim,
Enclosed are two envelopes marked #1 and #2. The slab in the envelope is the 1/2 of the gasket that we milled and molded. Maybe you can check adhesion of the slab and 1/2 gasket under the same conditions to verify difference, if any.
Please copy names listed below.
Respectfully,
