Well I am trying to decide weather to re-skin my 69 FB door shells, patch the rust that is coming through, or buy new doors. I have rust in the typical spots front and rear corners. There is also some coming through in the lower middle part. I am afraid if I just patch the problem areas the rust will be back in a few years.. Plus they don't make patches for the middle door section for 69's. If I re-skin the doors I can then clean everything up and rust proof the shell and skin. Plus new skins would get rid of my dinged doors as well. I don't think my doors are in bad enough shape to buy the entire new door. I could get the skin and cut off the bottom 6 inches or so and use that for a patch. I am also concerned with the amount of paint I have left. It was a custom color the PO used and he never gave me the codes for the paint. I only have about a quarter gallon left. This is about the last thing I have to do on the car and I am just stumped on the correct way to proceed. Any advice out there for me? Check out the link below for my rust pics.

Re-skinning doors is becoming a lost art... I thought about trying it once and stopped by a couple local body shops to get some pointers. After they stopped laughing, they politely told me that this was no longer a cost effective option in door repair and didn't have anyone around who could do that kind of work....

Huh? Couldn't do bodywork?

I doubt that "re-skinning" a door is even still in the insurance companies "Guide to Efficient Body Work" that seems to be the bible for most body shops.

If you can find someone to do the work or plan on doing it yourself, I agree that a re-skin would probably be more effective than patch pieces.

Good Luck!

Man, your doors are in great shape compared to mine. If you're handy at all with a cutting wheel and flat sheet metal, you could replace just the bottom section of the door. It's a simple patch - no complex curves. Based on what I see, the door is mostly rust free above the lower trim line.

On the other hand, I hear the '69 reproduction door shells fit very well. On a time/vs money scale, shelling out $600 for the doors might be cheaper in the long run....

I am pretty handy with replacing sheet metal. However this will be the first real surgery I have done on a very visiable part of the car. That's why I am a bit nervous. How yould you go about replacing just the lower section? Buy a full skin and just cut ogg what I need or just use stock sheet metal. I was afraid there might be a curve to the metal I would not be able to re-duplicate just right.

Hey buddy - this post is like deja-vu all over again ;)

First, I will just throw this out in the air... my painter (so called...) reskins a lot of doors at his shop. He really does do superb body work.

You could disassemble them yourself and blast them & rust treat them, then I could take them to Scott with you. I just imagine he will want to do this type of work thru his shop though - so you will pay shop rates.

And either which way you go, you will likely have to repaint the entire door. Though with a new shell you will need more paint to get the interior/inside of it as well.

Patching would be easiest to say the least. I would just worry if more rust will continue to appear later in other non-patched areas.

Give me a call if you want Scott's number.

Having reskinned many doors and after seeing your pics, I would first try to fix your doors. If the rust is too much to bare after sandblasting I would resort to reskinning. The 69/70 Mustang skins are a little tricky near the top front, but they can be made to look real nice. The trick is to fit the skin on the door frame while the frame is still on the car.

I know that many people like the repo doors. They aren't seriously bad, but they just aren't as good as the original Ford parts. All of the repo's I've seen have issues with the inner shell. They also do not have the lower reenforcements in the outer corners (where your doors are rusted) so its very easy to bend the corners. One other thing, the ones I got look like they were skinned by hand instead of using a press.

Thanks Chris..
I have looked at your site many times as a guide to figure out how to fix my doors. Looks like I'll be trying to patch them. I actually came across a full lower door skin from Paddock parts.. I might give this a try. I guess if I totaly F it up I can always get new doors.

my cousin bought some "lower door" skins from some place. not sure if it was Paddock. looked like somebody made them out of old furnace duct. Hope you don't get the same parts he did.

I vote for a re-skin. it would be a nice learning experience if you do it yourself (like leadwork) and will probably be more cost-effective if you have a limited budget

Sorry for the delay, been forgetting to post this for ya'.

When I talked to Scott - he said a typical shop rate/hour is 6 hours, per door, to do a re-skin. Their shop labor rate is something like 46$ an hour (he could not remember exactly) - So, I went with a conservative $50/hr X 12 hours labor = $600 bucks. Plus costs of new door skins - apx another $160 - 180 +/-.

I'm thinking patching may be the way to go for now. I would just be more concerned about the custom paint and lack of quantity. But when you stated that you had a quart of color left - is that a reduced/mixed quart, or just the unmixed color ?

That is unmixed color..So I think I'll have enough to to the lower portion of the door. Plus I have the GT stripes on the door which I'll plan on re-installing. I was thinking on using the top stripe as a masking point. There will ba a line there but the stripe should cover that up when all is said and done. Yeah I'd like to know more about the lower door skins. So far the only place I can find them is the paddock. I figure I'll call them first before I order. They don't have pics on their website, so I ordered a catalog. Maybe there are pics in there.

Yeah I have seen that site for door rust repair. I wonder if gluing in patch on would work well. Basically use their method with the backing place except use the new panel adhesives available to day. Isn't how new cars door skins are attached? This waoud avoid any heat warping issues. I can weld and have a welder, but I am not the best welder in the world. Anyone ever used that panel glue?
