[Tigers] Type of black paint for spare hole down bolt and washer

[JAMES ARMSTRONG]

Hello,
I think my initial sending of this note got lost between Dr. Mayfield‘s request for information on hood scoops and a gentleman that was looking for paint colors on air cleaners. Both important and reasonable, but I ask if I could get a brief answer to my question as well.

I need some advice on the type of black paint used on the bolt/washer assembly that holds the spare tire down on the Tiger.
Is it flat, matt, semi gloss, or gloss ?

Thanks in advance, 
Jim Armstrong
