I always have mondo respect for the dude hammering away in his garage late at night and having a go at doing almost everything he can on his ride himself.

Kudos Zippy, keep the pix coming man, great work ! up

Our guide coats usually come from a spray can unless we have some dark color available for the gun done the same way as Tony

More of the same kind of thing.
My wife eats lucky charms, and I only get the box.
But, if they provide any good luck then I'll take all I can get!

Yes, I could have flipped the cardboard over, but needed the plain side to face down because
that's where I made my pencil marks. So: It's "fun, distracting and unprofessional side up".

You'll notice the cut metal isn't anywhere near the size of the templates, this is by design.
The templates are supposed to be slightly oversize. Rough cut new metal to the template, hold securely in place, partially cut through both
new and repair layers at the same time, peel back the bad stuff, hold the new stuff in place and tack it.

Here it is flipped over, showing the side that will be visible when the door is opened, after the skin is installed.

Still needs rectangular bumper hole cut out.

Now finish rust and paint removal, 2-3 coats of epoxy in and out, prep the new skin with epoxy and a little sound deadener
on the inside, then the skin will be ready to install.

I could have bought complete door shells for $1800 instead of two skins for $600 and done all this work
(normally skins are $800 but I found both skins discounted, one locally at Roseville on sale and the other from Jegs
with slight shipping damage/edge dents that came out with a few minutes of hammer and dolly work).

Why not use complete reproduction door shells? For labor savings, complete door shells would be the way to go, but
I fit the quarter panels using these original doors,
would rather not mess up the gaps in a new way and then have to fix that, fix any other issues they may have, and plus these originals were plenty savable. No reason to scrap them for a couple rust spots, they don't grow on trees...its not 1982 anymore.

Looks good!

Wray Schelin's YouTube channel is also great for metal fab info. He hates bondo so he shows people how to take metal work as far as needed to make it right. He also makes the shrinking discs used for metal finish work.

I agree with the original stuff. Any body that thinks Goodmark or AMD just bolts on and needs a prime coat is living in La La land. Many times it's quicker to fix the old stuff than fit the new stuff. Great progress.

Hopefully this is not so exciting that it breaks the internet wink

Left door is coming along quicker than the right door, which I guess figures since it's the second one and
I had a better idea of what to expect.

Super complex and highly professional blasting rig came through again. $20 second hand pressure blaster with a few parts replaced.
As for the media, "Black Blast" (coal slag) from Menards is expensive but rips through the rust and coatings much quicker than silica sand.
PPE/Respirator required. 2 coats of SPI black epoxy. I would probably dip the entire car in epoxy if I could.

Interior of new skin, scuffed e-coat and applied a few coats of epoxy.
Next day, masked off and shot a thinner (lightweight racing?) layer of sound deadener just like OE, but less sloppy.

Added the rectangular bumper hole to the repaired area of the structure, hammered and dolly the skin partially into place, (not shown) test fit on the car to confirm gaps were correct, pulled back off, hammer and dolly work to finish the skin install, spot welded the skin to the structure every 6 inches or so, prepped/smoothed the welds. Flipped it over, removed ecoat, 3 coats of epoxy, minor filler work, sealed bodywork with epoxy, (shown) 3 coats of 2k surfacer.

Tonight, guide coat and blocking. I think I got this one straighter, earlier/up front than the other side.

Goal with every panel is to repair everything, block each individual part out to 220, then when all panels are to that point, block the whole
vehicle in 320 + whatever finer grit I'll probably decide to go with. Basecoat TDS says 400 dry, 500 wet. My sprayout over 600-sanded 2K looks nice. Will probably get some extra materials, and shoot a whole old door skin or the remnants of a quarter panel for practice and to decide which one really suits me better.

When this door is finished to 220 that will complete the first stage of my master plan for the exterior+ trunk.

Engine compartment, cowl, bulkhead and A pillars will come next.
The engine is still in the car, so that's going to require a little bit of work to pull the 451.
Being a sentimental idiot, I will need to hear it run again before it comes out
and plan to run plenty of fogging oil through it.

I love your plan, pretty much how i do it, but i like to use spray polyester. I like blocking the panels into each other (doors qtrs, fenders) then carfefully take it apart for paint . It gives you really nice body lines and super flat flow from panel to panel

Haven't any experience with poly primer yet, but after the multiple rounds on the quarter panels with regular poly filler on the fenders and quarters to get them straight, I can see now that maybe poly primer would have got me where I wanted to be, sooner/faster.

I'm probably an odd duck in that I'm totally comfortable with old stuff hardly anyone is interested in like lead/body solder and single stage paint, but have not tried poly primer.

There's always the next project smile

Thanks!

Thank you Mark! No rust, and straight are really my only priorities right now.

after that, the topcoat will make it or break it.
If nobody highly skilled offers to shoot it for me (which I assume will happen, given the lame response received so far)
then I'll have to buy extra materials, practice, develop something on my own and set up the shop a little
differently to do a makeshift booth. Tentative plans have been made and so on.
