with my engine bay i started with givin it a good clean!!! u'll be surprised at the difference it can make!! i have also sprayed my radiator brackets and my fuse box cover (both very easy to do). radiator next probably, just to get the rusted look gone!!! rocker cover also a good idea, but would be best lookin for a faq on removin it before startin it!!! should be a good project for u!
