Probably not. I turned down the recent rust warrnat on y wife's car because of this. According to tht dealiership the rust would have to cause a 'hole'. I asked them to quantify the term 'hole' but they could do no more than explian it would be a 'hole'.
Sounds, from my expereince (even drunk & dperessed), that they will only fix a major rust problem, which you would never see withing their warranty period.
My advice, try and see. See whatyou can find makes a waranty call .. then maybe help it along!
