IR reflective coating ?

I would like to do some special IR lightning. For that I would like a 3D printed complex surface being coated with a IR reflective material. Aerosol painting would be nice. I can’t find for the moment such a painting. Something that has performance like aluminium which is very good at reflecting the whole lighting spectrum.
Someone know something like that?

3M 7610
High gain reflective industrial grade sheeting, exposed lens, retroreflective plastic-based material
good luck. Best in the market

Thanks for the tip.
3M 7610 seems a very good product but tape is not what i’m looking for as the shape to cover is a non-developable surface and some areas will be inaccessible to fingers.
