I have to agree with 'thelocust', brass is the best stuff fort that kind of job. Use callipers to find out the right size to use or go by visual if nothing included in the kit. The beauty of brass is that when it is bent it has no memory so it wont try to go back to its old shape like heated styrene will.
Solder and a flux is great and if there is a little too much it files away easy, you can use it as a filler too on any brass.
Imagination is the limit with this medium!
