in spots the filler was very thin in others , like the area that started this thread I lost a nickel in it. No not flat I MEAN ON EDGE! What little I know about body work my dad tought me on my first car. A 1950 willy's war jeep...there was not a round corner on that thing and that long board keeped a young kid from tipping the DA on it edge, and thats a trouble spot for a lot of beginners I think. At least it was ( is ) with me. Thank for the help
