67 Dart daily driver........undercoating

Hello everyone.............I would really like your opion on a matter. My plans for my 67 Dart is to drive it..........I know it may sound stupid to clean off all the undercoating and then ask a question? Would you reapply it? Like i said......Im going to clean up the car and plan on daily driving it .Like your opinion on this ......Reapply the under coating to fender wells and underneath. Thanks of course...........To me your wisdom and opinions are always welcome......................Thanks Edd
