Were listeners of your show and heard you guys telling a listener that there is no need to rust proof your cars anymore today because cars don't rust today.Also you told them to get the dealerships to spray there black rubberized sound deadener on there cars all that stuff is a faster way to hold moisture and rot there vehicles faster then ever.We at Krown have been rust proofing cars for over 25 years and we study new vehicles and we find that todays vehicles need oil based rust proofing more then ever today because of the cheap way they are built now.Nothing is welded anymore everything is pressed and use a speacial adheisive to bond doors,hoods and other seams.
