OP - that's too bad! Sorry!
A quick question you might have an answer for?
I'm confused but one side cover looks like custom paint job while the other looks black?
IME, unprotected lacquer paint is very vulnerable. Where as enamel can handle a bit more chemical abuse, followed by hardened enamel such as a base coat of color and clear coat of 2 part hardened enamel.
If I had to guess instant contact would only take out lacquer so quickly so I'm curious what you know about the final top coat as far as what it was.
Thanks and again, sorry! Thats sucks!
