Metal Roof Condensation

[karoc]

OK don't roll your eyes, yes I know this subject has been beat to death but!!!!
I also want to admit that I am so gullible,let me explain. I just watch another Youtube about stopping condensation on bottom side of metal roof. So I wanted to ask if this is a method that is for real as a solution. The Youtube showed guy who painted the underside of his metal roof. Never heard or read anything about painting,so maybe its fake?

The paint was to stop the condensation?

It is,the guy did not spray one half but spray the other half. That morning the unpainted side was sweating and the painted side did not. Never heard of this till today,lots of Youtubes each one trying to sell their product to cure condensation.

Was the sun shining on the half that was sprayed, bringing the metal temperature above the dew point?

What do ya'll think about this? Example only. Finn that I don't know,but looking for that Youtube so I can provide a link. I don't know what kind of paint he used,but that Rustoleum paint looks like only available in UK

Google anti-condensation paint. It apparently absorbs water condensation and prevents water from forming on the surface. I guess that would be up to a point where it could be saturated and no longer absorb the condensation that was forming. Looks like no "Pinocchios" on this because it looks like it would work......up to a point. Surprised me, though.

I be dang,that's not good. I will be checking into that vinyl insulation foil back wrap which I think is better than the white vinyl insulation.
