Maybe Expansion Foam, Its used by tradesmen for aircon ducting & the likes, its strong, durable, weatherproof and bonds to just about anything. You spray an amount and it will expand approx 5 times the size. Hardens in an hour then can cut with hobby knife for neatness and sand for a paintable finish
