I'm 65 years old. I figure the bondo in my hot rods only needs to last 10 years before I'm relegated to the rocking chair. Let the next guy fix my work after he gets the car at the estate sale.
This thing can be locked at any time so are we any more informed than we were? I think these"debates" are good in that way we will invariably glean "1 percent"- good information from any 1000 bondo posts! A point I meant to mention earlier is that an equally important thing this metal repairing can result in, besides eliminating all plastic..... A repair done in the manner, described above as having a TON OF HOURS- or even the 100 hours work in metal finishing on one panel...[I DO believe it]....But I would have to imagine there may be some WORK HARDENING, occouring from all that HEATING/pinging /shrinking/ planishing/ english wheeling, yada, yada yada, that was employed in the ALLLLLLL Metal repair...... I have saw this condition in cars that have merely been sandblasted a couple of times,so its not beyond the realm of possibility that this working and even "overworking" of the damaged panel,could give it a shorter life span than even a "bondo job"- because of resulting fatigue or hairline type cracking that results......
all i can say is..if you don't know , i can't explain it to you 5 pages of excuses for and against we all have to find a level of bondo we are OK with bondo is just thick primer
