Dont just cover it up mate that get rid of it. Is it just surface rust? If so rub it down prime it and paint it. If holed? Best to cut it out and replace with good metal.

The only real way to get rid of rust is to cut it out, and replace with fresh metal. Cleaning, treating, waxoyl etc, will slow it down a good deal, but it will continue to break down the metal..
For things like stone chips or minor issues where the rust hasn't penetrated, a good quality inhibitor followed by primer, and then paint should be a lasting solution. The surface must be bone dry underneath though, as any residual moisture will continue oxidising and eventually lift the paint after a year or so.
Do not brush paint, always spray. Even if it looks like an even cover, it won't be and moisture will find its way through the brush strokes and get back in.
Don't leave rust repairs in primer or matt paint either as it's porous, and again, moisture will get back in, and you'll be back to square one again!

As Junkie says... cut out the old and get new welded in. The only way to properly do it otherwise it will always come back.
