I had 4 pieces of foam sent to fill the order and this meant more work and filler. The 2 sheets were attached with Alhapoxy and micro balloons and then 2 uni cloths with structural resin to finish the job. The foam had 2 layers of cloth because this will be the weight baring area for the luggage and I wont it to be strong and not flex. The foam is ¾” thick and this will help keep the noise out of the cabin I hope.
