Good job. At least we all know where the warranty issue stands.
But as things go, I can't remember anyone ever submitting a claim for warranty paint issues. Galvenized steel has pretty much made early rust a thing of the past.
So I guess that would mean that if you're painter did a poor job and got overspray on a rad hose which eventually leaked causing your engine to overheat and the pistons to seize....that your rad, hose and engine would not be covered under warranty.
I know...I'm reaching for the cause and effect...but while remote it is still a possibility.
