RE: Ca hinges and Kougar...
I doubt that the little amount being put on will effect it enough to worry about it but if u have any extra foam try a little and see if it eats it. I'm building a King Kobra and I will be using dubro pinned hinges and I will be using gorrilla glue to glue them in. I did this with my Goldberg Ultimate and it worked very well. Grabs insanely strong!
