Lots of talk about gaps on many forums on the ole interweb but I don't see much about getting panels flush with one another. Is there a good or preferred way to get panels to lay flush. in this example I'm trying to understand and develop an approach to getting this fender and door to cooperate with one another. every other panel and gap is manageable but this one is boggling my mind. Can anyone offer any good advice? I though about slicing the inner structure of the fender and pushing it in a bit then welding it back up but thats about all i can think of. Surely there is an easier way? hopefully the picture will help explain.
