Profiling Panels

Hey friends, I'm mocking up panels and such and desire a very straight car. I ran a straight edge over the back edge of the doors where it meets the front of the rear quarter panel (See pic for clarity) and I get some bowing in of both the door panel and the quarter. I have an idea on how to address the doors but aside from filler, which I don't know that I want to do, how does one address the rear quarter? Thanks!!!

Assuming your door is installed correctly, and not having knowledge of that year Mustang, the rolled in edges may just be how it came from the factory. Many vehicles came from the factory with rolled in edges. If you don't want the factory rolled in edges, you're going to have to do what your contemplating.

Sylvester Customs on Youtube shows how he blends the doors to quarter panels for a perfectly straight panel to panel profile on a 55 chevy. Those cars came from the factory with rolled in edges.

My Mustang looks similar. I too am trying to figure out if it's supposed to be that way. I have some welding rod welded in most gaps, and I believe the welding causes shrinkage which would pull the edge in. So maybe the welding caused all of mine, some of mine, or possibly none of mine (I did go real slow).

Unless you planished the welds, your welds did shrink the metal. Door edges are easy to planish, quarter panel not so much. Not saying quarter panel planishing can't be done, it's just not easy due to working room .....imho.

Usually, such "rolling in" with a taper is done for added strength on an unsupported edge--it is a desirable thing to leave as many were engineered this way. Any skim fill of dissimilar material (body filler) is a potential failure waiting to happen close to an edge.

Learned something new today. I didn't know that. I assumed it was a casualty from the manufacturing process.

Thanks,

Not to get too far off topic but, when you used the word "taper" ....... that made me think about all the effort and time spent shaping edge welds with a taper to look line a factory edge. I had to do this on my door edges and trunk lid. What a time consuming pain in the a%%.

I've heard that before and it makes sense. I'm still weighing in on whether I want to jack with it. Thank you for your response.

I'm subscribed to his Youtube channel and I've seen this video. His videos are great and he always answers questions. Good luck in your project!
