I've used my thermal imager only a couple of times now in the line of duty and already encountered the "emissivity" problem. Doesn't accurately measure shiny objects. I was thinking "if I had an acetylene torch, I could just turn off the oxy and coat this bad boy with black carbon, that would wipe right off." But I didn't have a torch and even if I did, I don't think my customer would get a warm fuzzy feeling watching someone who they undoubtedly presume to be a mechanically incompetent wire biter aiming a flame axe at their megadollar extruder barrel. Plus I wouldn't like to carry around heavy bombs in my car all over town either when they would be rarely used.
So I want something less crazy; I'm imagining an aerosol can full of some magic substance like the carbon that a torch would deposit, or a jar of dust thats brushed on like how they dust for fingerprints in the movies. Something that wipes right off (or blows off with compressed air would be better) and won't cause problems for mechanical devices (ex: a gritty powder that would damage gears) and wont cause problems for electronics (nonconductive). Maybe a colored tape, but preferably not; I foresee issues with it not conforming to changing surfaces (anything that's not flat) and not sticking well to oily surfaces or melting to hot surfaces.
I this sort of a preemptive request. I haven't dedicated much time to researching yet, thought this oost might save me some time if anyone here knows what I'm talking about and where to get it. I looked briefly and everything I saw was high emissivity permanent coatings.
