well, I appreciate the input - but the car bra analogy is a little off; bras caused paint damage from buffeting, mostly. (80s highschooler here - intimate with bras)
You've missed the point.
Someone commented on alloy checkered plate being taboo on 40s, it's because it used to be done commonly to protect from damage and supposedly looked badass, but left many otherwise good 40s tubs with rusted quarter panels, and panels full of rivet holes.
The analogy is that the very thing that is supposedly protecting the pristine panel destroys it.
Same with car bras, even if the mechanism that does the damage is different.
If the panel is not pristine. Why bother armouring if?
Each to their own.
