Cut out 2 plies of BID at 45deg orientation to make two 2″ x 17″ pieces of fiberglass tape.
Workshop temperature was 25deg C and humidity 33%.
Mixed a batch of epoxy using 116g resin and 44g hardner. Poured a small portion into a cup and added flox.
Applied epoxy to the 2 ply layup and applied flox to the joint between the seat brace and heat duct to ensure it was smooth.
Cut out the 2″ x 17″ BID tape using electric scissors and applied them to the joint on each side of the assembly.
Placed peel ply over both joints and wet it with epoxy.
