I agree with Boatshed,
My two 'go tos' are Deluxe Materials Canopy Glue and Glue 'n Glaze.
Grip well, dry crystal clear, don't fog clear plastic and don't stink of cyanide gas 🙊😝
Canopy Glue is good for sticking to painted / varnished surfaces.
Glue N Glaze is better for sticking to metal.
Don't get too stuck up Jim 😮
Cheers, Doug 😎
