if in the worse area of the corrosion you think it goes as deep as 2/3rd of the bar I'd say scrap it or use it as a coat rack. It only takes one bad crack for the bars to fail and it's not something you want happening when you're riding.

Curious [MENTION=112127]johnnytheboy[/MENTION] , is that white stuff actually eating away the material of the bars or is it salt or something that's just built up on top?
