Thank you. I have done some body work in my younger years that I would not be proud of . I had a work truck that I did body work on that I drove on a daily basis and didn't see any problems for a couple of years. That was without proper treatment . I'm sure this type of repair would have lasted much longer.
I doubt this car will see much time on salt covered icy roads , so it would be hard to make a comparison. One thing that is for sure is that if you repair this type of damage using " conventional " methods , putting the car back to or close to factory conditions , you are putting it back to what we know failed. There is no doubt on that.
But a person has to be realistic and not compare their work to other work that wasn't done the same and didn't have preventive measures taken.
Depending on how a person is going to use their car is going to determine how long their repair lasts. If a person repaired their car in this fashion and it saw the same use as many classic car , I'm sure there wouldn't be a problem .
But, we don't see fiberglass repair work that much thought was put into it . We don't see fiberglass repair work that was treated and sealed from the elements so there is no comparison . We have seen fiberglass and metal work that failed and either method will fail again if put under the same or similar conditions .
This type of preservation or build or whatever one would call it is doable by many more people and affordable by many more people and may be a more common sense investment depending on the vehicle . It wasn't a matter of affordability for me , but rather a preference and I wanted to encourage people to do something with their car if it was in similar condition as mine.
Some people will use exaggerations to condemn this type of work when they have no comparison to what I've documented here. It's not an exaggeration that some are working on or have worked on a car putting it back to a state that we all know failed. I think the treatment of a car after a repair is a bigger factor than what method was used in most cases.
And that is the reason I followed this & commented positively & called out some that hadn't read your reasoning.
And I said, about my own 65 Barracuda that I'd Ospho-ed(phosphoric acid) & Miracle Painted(early, possibly original POR type) the underside & painted it before cured.
What I never went into was car was solid but rough, with repairs done in late 70s.
The son of the original owner is my friend & car came from Scottsberg Indiana, so winters took a toll. I just want a driver so I wasn't real worried. He had told me it had been 'Jumped' over a Railroad track crossing out in the country and was then repaired.
After I got it home(traded a 1965 20' Chris-Craft, for it plus a slant 6 parts car) I saw some strange repairs. Had seen the bondo was floated between rear windows & bubble window & loose in spots, so I assumed it had damage there. Also behind doors.
Before painting bottom I checked frame & it had been straightened, so I rebuilt front suspension & painted , removed chrome, fixed dents & mulled it over, & decided if i removed all the bondo I might find too much ,so..
I drilled 5/32 holes in the bondo, where loose. Then injected it with ospho to stop the rust & then miacle paint to seal it.
Then I injected it with West System Marine Epoxy, thinned w/Acetone to be sure of full penetration(heat helps too), then followed that with the same Epoxy with fillers to thicken it, still fluid enough, and some thicker. That loose bondo is now solid, so I could move on.
RH lower quarter & ww lip was repaired, w bondo before i got it.
Still haven't done the left. Had to move my Mother, she died, had to move all her stuff again, moved to Florida & moved again down here.
Not worried about originality either, as they'd neglected the Anti Freeze & froze the original 273 & put a 72 318 in it.
So everything you've done is totally understandable to me.
Now the bashing will begin anew.
Don't Care!
