Getting started: tools? Tips please!

Van Damage I've got it under good authority that it is fine... what about any tips on reducing the future damage of rust, or preventing more... without getting it re sprayed?

i'd use use some clear waxoyl (from car shops - halfords etc) inside the frame and clear coat the outside with a couple of coats of laquer and it'll stop it getting worse but still look hard as nails. i've used this on cars and it's worked well. :-)
