.I'm scratch building a 22" tinplate hull at present.Must research best adhesive to stick large areas of ply to metal(Gorilla glue?) Seen it, never used it!
in my humble opinion Rodeo I would leave any form of gorilla glue alone...……
I have used the brown stuff that is moisture activated, the white wood stuff that has the sticking power of chewing gum...….the cyano acrylate is too brittle and a knock dislodges it easily, and the laminated duct tape...…...has the sticking power of toilet paper.....I have used all four to try them out, and have always gone back to my old faithful's but don't take my word for it, after all I was only a woodwork/metalwork teacher for 22 years.
however, my favourite when I was gluing ply to a steel deck that I was putting on a steam trawler 32 years ago was a specialist 2 part epoxy specially made for steel to steel and steel to timber, and tested to 100c...….it was expensive even in those days, but it stood the test of time and the model I used it on has been in Fleetwood museum since 1988 without any delamination.
