look for something with titanium dioxide in it

[The Cannarchist]

"Titanium dioxide is the most widely used white pigment because of its brightness and very high refractive index (n=2.7), in which it is surpassed only by a few other materials. Approximately 4 million tonnes of pigmentary TiO2 are consumed annually worldwide. When deposited as a thin film, its refractive index and colour make it an excellent reflective optical coating for dielectric mirrors and some gemstones, for example "mystic fire topaz". TiO2 is also an effective opacifier in powder form, where it is employed as a pigment to provide whiteness and opacity to products such as paints, coatings, plastics, papers, inks, foods, medicines (i.e. pills and tablets) as well as most toothpastes. Used as a white food colouring, it has E number E171. In cosmetic and skin care products, titanium dioxide is used both as a pigment and a thickener. It is also used as a tattoo pigment and styptic pencils."

... so whats better that white plastic sheeting (aka panda plastic) or mylar?

[billybigbud]

I am painting a cabinet so it would be to hard to line with mylar.

I a bought bear ultra white flat. 22 a gallon. cant beat that.

Their use to be a thread on the old cw were some guy used a light meter and did test on all kinds of reflective material. to bad I can't remember what it said

[The Cannarchist]

Basic Matt white paint with Titanium Dioxide is just as good as Panda film or Mylar.It's only a percentage point difference in reflectivity yet way cheaper.

Yep, good old titanium white paint...
Even painted on metal and glass coated for reflectors...

Mellinex may also be an option. It
