1959 356A S/R coupe project chassis # 108625

Switching gears. The body is now ready to come off of the cellette bench so it can go back onto the rotisserie to finish out the remaining chassis repair details. Before it goes on now was the time to finish out the front and rear bumper fitments.
Wire wheeling the last of the filler and primer coats this front bumper came with. I would have left it but I found flash rust growing under the plastic filler that was applied directly to metal. This is why I always use an epoxy sealer base first. Bondo absorbs moisture and will wake up any trace amounts of rust if there isn't an epoxy barrier between the two.
Redoing a poorly repaired rust spot that formed under the deco. No repair patch, just flooded with weld and is very porous and brittle. You can get away with this approach on small holes but this one was way too big for that. I get the attitude behind this repair though, these small annoying chores never seem to end and it gets to point of " UGH! another damn hole; to hell with making a patch, just flood the damn thing closed". Its a temptation that can be hard to resist at times especially as the long journey of metal repairs gets towards its end.
Reamed the entire weld out with a step bit and now adding in a new patch.
Welds ground down, then picked and filed. All done here.
One more to fix on top where a license plate bracket may have been mounted at some point.

Front bumper continued:
Outer shell completely cleaned back to bare metal to ensure I got all the flash rust that was forming under the bondo. Now onto pecking out the obvious dents and lows spots that were left behind.
On the flip side a couple of the capture nuts needs some attention.
Then it was onto adjusting and fitting these new irons to this project.
I needed the bumper to able to slide over to the right a littler further. With both halves of the iron installed this eyelet was maxed out. I had three option to get around this: I could file the eyelet open further but there is not enough meat left on its end to allow that. The entire base mount could be removed and remounted over to the left a touch to center that capture nut in the eyelet or the last, easiest and least invasive option was to remove the capture nut face plate area and index it over.
This capture nut needed repair anyway so it was cut out. A new face and nut is ready to go back on here. It will be indexed over to center it in the eyelet for maximum adjustment options for the bumper.

Thanks for looking.

Justin its always great to see the job being done properly as you have done with the rust hole. Its why restoration done well will always be expensive none of these repair jobs can be done in 5 minutes the hours soon clock up.

Hey Roy, Thank you hope all is well with you! Yes, all these little repairs can side track things a bit but in the end it all has to be addressed eventually. Thanks! Justin

Finishing up the front bumper prep:
New capture nut tacked and indexed over where needed.
Now both sides are more centered in the eyelets allowing for any needed lateral adjustments with the front end.
Now onto cleaning the underside of the remaining old paint scale and rust.
A bit of work eventually got the entire underside clean along with the in and around areas of the mounts. While cleaning I noticed that one side of this blade was completely different color as the other half once I got past the top coat of primer. It became clear that this was two dead bumpers mated together to make one. No wonder the profile shapes were off side to side in the beginning.
One more full mock up with the car. Best adjusted position with a good consistent reveal all the way across. First test passed. Now for the second; adding in the jewelry for its final test fitment.

Thanks for looking.

Finishing up the front bumper.
Trying out this HD industrial epoxy sealer system I got from a buddy of mine. Its recommended for heavy equipment exposed to the elements. Once I confirmed that my tops coats where compatible with it we bought this system. The sealer is off white and the activator is the green stuff. Both are very high solids and mix very much like JB weld. Its direct to metal and can be brushed on or thinned for a spray gun. Mixed it will yield over two gallons. The entire underside of the body will be sealed out in this coating. Probably overkill for the life this car lead but added durability will be nice for peace of mind.
Mixed a cup of it straight with no thinner and brushed a heavy coat of it on to fill in my lead divots and other obvious imperfections. Once it cured it was block sanded level and is ready here for another overall coat of it thinned for a spray out with my gun.
Second coat of sealer was applied then followed up with these thin swatches of putty to catch the last of the rough imperfections.
Putty was blocked then sealed again then a work coat of white enamel was applied. Still some rollers to take out but this was as far as I needed to chase it. The body shop can take it the rest of the way. Reassembled a with all the trim for one final mock up.
Then one last test fit to the car itself just to make sure there was no surprises for the owner or the body shop.

Last mock up
Now onto the rear bumpers' final fitment.

Thanks for looking.

Begin rear bumper fitment
Original bumper (not to this car) and a new reproduction bumper iron set.
All the threads had to be chased first.
Initial mock up.
A bit of shaping and rebending before these fit to the bumper much less the car itself but its a starting point.
Turned the car around and dismounting my rotisserie rig to prep the car for its new rear bumper.

Minor residual crash damage:
Bottom skirt needs a little ironing out. The back end of this car has never been hit hard but it was nerfed at some point causing some minor damage to the skin
and to the corners of the chassis at the bumper mounts. The forward hole has been stretched outward from the impact.
Eventually got it pounded back into shape using this square stock clamped into position as a bucking board.
Corner of the chassis all squared back up with the new bumper irons fully bolted down for the first time.
Similar damage on the left corner but a little lighter. Repeated the process on this side. Notice the upper strut tube mounting tabs have been pushed downward as well. Easy fixes thankfully.

Justin the front bumper looks great now and the back one should turn out well for you. A lot of work though on those bumpers. As I have said many times lucky my car had bumpers in good condition when I bought my car 56 years ago. So they are still okay now

Thanks a lot Roy. We were expecting the rear bumper to go even quicker but as it turned out it became more of an in depth dive than I could of imagined. Will be posting that up here shortly. J.

[JTR70]

Rear bumper trial fitment:
Irons on both sides mounted for the first time.
First test fit. Notice how wide this bumper swings away at the corners. I didn't realize it yet but this would be the beginnings of another in depth detour/ learning experience.
Tilts upward a touch but again this was just the jumping off point.
Could only get one bolt started on each side but it was someplace to start.

Lots of reshaping and incremental adjustments to come.

[JTR70]

Bumper iron sculpting:
A brief and small window into what turned out to be a constant repeated process of shaping these irons to not only fit into the bumper mounts flush but also allowing for maximum adjustment at the eyelets while holding the bumper centered with the desired reveal away from the tail and at the right pitch.
Above shots are just two examples of what turned out to be many, many holding hold jig configurations to heat and manipulate these heavy pieces of steel into the needed shape and length.
Eventually got a flush fit into the bumper mounts but as you can see that was only a start. The ends are cockeyed and need some twist at the tips so they'll run parallel from side to side with one aother. The eyelets on the frame side of this mount are nearly even at this point....
but once the ends where heeled over to meet the pitch that is needed for a flush fit against the chassis the tail length and eyelet alignment went completely out the window. The eyelets on the bumper side are also bottomed out against each other locking out any lateral adjustments options that may be needed... back to the drawing board.
With the pitch set and the ends brought back to open and even the end on this irons' eyelet was way out of range. This would require another round of give and take from both halves to dial all of this in to where it was needed. Again, this was just one example in a long series of repeated adjustments and mock ups to get these to fit properly. After it was decided that the bumper needed to be modified this process began again... all of that a bit later.

Thanks for looking.

Bumper Iron finishing After several sounds of heat and readjustments to both halves I finally had the needed approach angle along with the eyelet alignment I was after.
Repeat left side...
Towards the end of this sides' process I ended up with about the same issue as I did on the right side; oh well at least I was consistent. Onto another round of give and take from both halves to get this issue smoothed out.
First full bumper mock up with fully bolted up irons and chrome trim.
Begin introducing the strut tubes for further fitment and locating confirmation. A little more residual old crash damage discovered as the mounting tabs have been downward.

Thanks for looking.
