- Mike sanded area around bulkhead at station 155 & prepped the aft side for application of 1-BID. - Rick applied 1-BID to aft station 155 bulkhead. - We attempted to applt 1-BID over 3/4" spruce stips on cockpit area, but wood evidentally absorbed some acetone - which prevented our layup...so we'll wait a day or two for it to dry up.
