Helping a friend who wants to paint his car himself... I'm just providing guidance.. We've started stripping paint, gonna take everything down to bare metal... I'd noticed there was some filler on both front fenders... I hadn't put together why... Now I have... They brazed up some emblem holes.... Then bashed the area down & mudded her up... A little hammer & dolly work would have gotten it down to less than a teaspoon of filler... Instead the whole area was over 1/4" thick.... Honestly if they had just blocked the mud till a few high spots peeked through it would have only been 1/8" instead the whole area had an unnatural crowned shape.... Both fenders were this way... When it's done there'll be less than 1/8" of filler...
