freshen up tired original paint 68 barracuda...

Hi everyone,

I have a 68 barracuda with original gold paint. The paint is old and faded but i wonder if there are any methods/techniques on how i can freshen it up without repainting. There are also several small spots with surface rust and I wonder if I can sand them down and touch them up as well? I'll be the first to admit that although i am not afraid of getting my hands dirty, i know absolutely nothing about paint and body work. Any tips or suggestions on how to clean this original paint job to show better? Thanks!
