Model planes for me but I used this glue, it was a liquid and would melt the plastic. It was called EDC (some big long name) My dad called it Extra Darn Careful because it was toxic as heck but worked great. Fit the parts together dry, touch the seam with a toothpick dipped in this stuff, and it would wick along the seam melting it as it went in seconds. Let it dry for a minute or two and you had one piece of plastic.
Never heard of EDC. Sounds like it required a lot of precision and attention to detail.
Since we're confessing here, .... uh ....
I currently have several kits in various stages of assembly.
Go YOU!!! I look at them if I'm passing by. I have a lot of my models boxed up in someone's basement in Michigan.
I built model cars as a young teen, then built mainly WWII tanks and planes after that. I was hella good.
I built built mostly cars/trucks, but I did build battleships, too.
