Hmmm in that case I think i'll keep chrome usage to the very minimum! If it's this fragile to use, it's not really worth using (not that I was really planning to use it very much anyway). Luckily it was only a really small area on the shell, and i've managed to repair it (I had to spray a light mist of silver on the outside of the shell), so i'll just use the body as more of a runner than a display shell like i'd planned. It's just a pain when you spend so much time doing a shell.
Now I just need to work on some more graphics/sponsors for the shell
Thanks again for the advice guys, it's very much appreciated.
