I use a brand called "Fusor" for all my chemical bonding. They have a whole range for bonding metal-metal, fiberglass-metal, slow dry, fast dry, etc.. etc... It's what every shop I worked at used.
I believe that metal to fiberglass is Fusor 127EZ, but I'd have to go look.
I hope this is what you are asking, as I'm not too sure about the question. Did you want just a brand of good chemical bond or an actual design idea?
