As I'm scraping off the old undercoating from my '59 front fenders to do metal work, I began thinking of how well this preserved the metal.
If the original owner paid extra for this, I think I'm the benefactor.
I want to apply something when I'm ready for the finishing part of this project.
One thing that came to mind is truck liner... else I was thinking primer.
I decided to pop in here to see what you guys thought. What did you use?
