Mike,
we all know the least filler ya can have is best , especially in front fenders ,they take beatin from road debris and flexin from the wind ..be best to massage them out best ya can to get rid of as much excess filler ya can ...or your new paint job ...lookin like a million will turn into CRACKS and rust that you will not be happy with 6 months down the road after water gets under it ..
work out the metal as best ya can before puttin 2 inches of BONDO on it ..
