How many people would like to find out what their IR reflectivity index is of their paint ?
Seems I could build a simple device with an IRled and photo-transistor in a cigarette sized box that you could set on a flat section of paint and measure its IR reflectivity (multimeter or volt meter ) Have a little soft rubber seal that prevents external light from getting in. 9v battery , push button.
Could add another data point for reference for the MOAC perhaps?
(begins to build said device)
Anyone want one?
