I'm not sure if the above Dali link is an epoxy based or not. I think it is. I would recommend an epoxy based paint. That means paint with a hardener so it cures, not dries. I did mine in black and used red to paint the letters "NSX". If your car is Red and you want to paint the calipers Red, I think that would look nice. Some people then file the paint off the letters so it says NSX in silver color, I would suggest getting some black as well and painting the NSX letters black. I bought my paint from a mail order catalog, but I can't recall the name. I paid more than the $39 Dali price, I think it was $45 per kit that I paid.
Good Luck
BTW, it was very easy to do.
