1. My paint shop charged me for priming,,, and I just realized these spoilers come primed? Did I just get ripped?

2. My spoiler did not come with installation hardwares(bolts, nuts, etc)
Do I go to ACE or Homedepot, or Nissan dealer?

 

They do come primered. At least the real Nismo wings do, you might have a replica.

They should come with everything, including mounting templates. But again, that's just with the Nismo made-by-Nismo wing.

 

I have a CF replica and I bought the bolts from Ace. Just take the base down there and see which bolts thread into it.

 

Mine is authentic USDM nismo. It came with the template, but the seller didn't have the bolts. But the online vendors don't have the bolts, so I was wondering if I can get them in some other ways
