Removing & stopping rust.

[greenhorn]

This is the 2003 GZ I bought for $800. It is my commuter ..I ain't in it for the beauty. How can I go about removing this rust & then treating the area to stop it?

I need to know:

1) How to remove it & how to treat the area to retard it.

2) Product info./ brands

I would prefer NOT to paint. My main goal is to stop it and then apply something to stop the progression.

Thanks,

M
