why is it that when i spray a clear coat, it comes out brownish or yellowish? is it too old? what can take off permanent marker besides paint thinner?

i'll answer your second question:
you can use rubbing alcohol, nail polish remover, or HCl (hydochloric acid) but you don't want to use HCl, cuz it will burn your car's body.... thats not good :p ....
