Best spray paint for IR (NIR) CCD Camera?

[Elgin Clock]

Are you restricted to a painted surface? Can you use a vinyl material?

I'm sure some folks who responded before me already can shed some info on the subject, but in our world of robotics on this forum, our camera we used which tracked color had a lot better success with a lighted surface than a vinyl surface than a painted one.

The camera tracks light awesome (most of the time). - Best medium so far.

Vinyl (which was reflective enough) semi-decent.
(My team personally had good luck with this the first year that medium was introduced as a tracking material)

Paint (on cardboard, or wood) was horrible to track.

I don't know if the camera you are referring to tracks the same as ours, so hopefully the engineers/mentors/teachers who responded before me can relate this somehow.
