just to add my two cents-and believe it or dont-diet cola is an excellent rust converter. good for cleaning eyeglasses and toilets too. i say diet because the regular stuff leaves sugar behind. thats what i used in my trunk. wirebrushed what i could, poured a two liter in there, brushed it again the next day, (all the rust turned to black iron) poured on some metal prep after using a shop vac, and painted. paint still looks good after 6 years. the diet cola treatment is an old family secret discovered on accident, i'm told. thirsty?
