Will I devalue my snorkel hood scoop by painting it black?

I suppose value is in the eye of the person willing to pay you for it... I would personally pay more for a reconditioned, smoothed out, color-matched dual snorkel rather than a choppy, faded, rough unit.

Just my $0.02.

I have an original OEM dual snorkel scoop going on my '73 Swinger and I personally plan to sand it down, smooth it out, and apply a nice semi-flat or flat black coat to it.
