Whats the best way to take care of rust problems and treat the areas affected?

 

Depends on the amount of rust, how deep it is, where it is, and lots more information. Some pics would be helpful. Welcome to Yotatech by the way!

 

if its just surface rust thats not to deep.. jsut grind it off. it its completly ate out like my bed was, cut it out and weld new metal in. or just buy parrts off another yota

 

check out toyotafiberglass.com he is a member here with several rebuild threads. does supernice work from what I have seen in the forum, he is a Canadian, so shipping is going to suck, but dont hold that against him.

 

I would....

 

agree with the toyotafiberglass.com recommendation for big parts. Like others..pics are the key to get correct advice around here...!
