i've read a lot of good stuff about ras-o-nil. i haven't had the chance to use it yet. apparently it works very well at converting rust and increasing weld strength. it's also non-toxic. they have a website but unfortunately i can't tell you their exact address. i think i found it as a link from another page. <a href="http://www.rasonil.com?" target="_blank">www.rasonil.com?</a>
