any tips to get rid of rust i dont wana bondo the wagon i have heard some people talk about fiberglass?

Depends on how bad it is...

Can you post some pics of the affected areas?

If it'* just surface rust, a typical repair would include sanding down to bare metal, removing rust completely, priming, and re-painting. If it'* a rust-through situation, then the best long-term method is to cut out and replace metal.

I know a lot of people who did the fiberglass patches and bondo, but rust came back soon after. Whether it was improper use or just the nature of rust, the above post is the best way to fix it.
