[Tigers] Cowl screw

[awtiger at cox.net]

Hey, guys:

I've been a Tiger owner now for coming up on thirty-five years and yet I can't believe I'm going to have to ask this question.  There is a pan head screw on top of the cowl on the driver's side right above the firewall.  I've never known what this was for, although I speculate that it was used on the Alpine as a ground point (maybe?).  The question is a two-parter...first, what exactly is the screw for and, second...is it supposed to be painted the body color or left natural?  

Thanks much,
Andy Walker
