New trend to have anything sticking up from the roof painted black

[Mike Canter]

I stand by what I have said in regards to heat radiation and the color black. You are talking about heat reflection. Two differnt things.

Excerpt from the Wikipedia entry by the General - My highlights

Lighter colors and also whites and metallic substances absorb less illuminating light, and thus heat up less; but otherwise color makes small difference as regards heat transfer between an object at everyday temperatures and its surroundings, since the dominant emitted wavelengths are nowhere near the visible spectrum, but rather in the far infrared. Emissivities at those wavelengths have little to do with visual emissivities (visible colors); in the far infrared, most objects have high emissivities. Thus, except in sunlight, the color of clothing makes little difference as regards warmth; likewise, paint color of houses makes little difference to warmth except when the painted part is sunlit.

I think that the confusion comes about because radiation is ABSORBED, converted to heat, and then CONDUCTED and stored in the case of metal, such as a car roof.


In any case, let's get back to the original question. I vote for contrasting pin stripes on all roof accessories, as well as gold plating on the Alcoa wheels and the French doors on the fridge.

Can you say "Pimp My Ride"?

Bluepill?
I agree with your fashion approach and also plan to pimp my ride, in my next life!

More specific excerpts:

The operative word is sunlit!
If an RV Mfg ever makes a black roof, I will ask the neigh sayers to place their butts on the sunlit roof for their own well done butt roasts!

We can agree to disagree?

At this point I don't think that anyone is really going to change their opinions.

I would, however, like to make you all agree that my choice of motor oils is the only possible one..................

And for the curious, radiators, condensers, heater cores, and evaporators are pretty much all 100% aluminum these days (with the exception of the glass-filled nylon tanks on the radiators.) Condensers & radiators are sometimes painted black, but that's a cosmetic request by the customer. (My last job was engineer at a heat exchanger manufacturer)

Do you think it may be because the UV additive used in plastics is black? You can buy black UV resistant wire wraps but I have not seen white or tranlucent ones, same with the wire loom sleeving used vehicles. The old white covers did not stand up to the sun very well. Don't know,
just a thought!

Also if you have to replace any of the attachments you don't have to match it with the coach paint.

RJay ....You have my vote...In the material handling biz primarly forklifts..they paint the upright or Mast matte black this does two things ..it reduces glare and your eyes do not focus on but rather look thru it or past it..and hence "take away the prominence of the roof attachments".....Thats my imput!....Great Forum!

You got it Rapid Robert - black lasts better because it is not so prone to UV damage.
It would be interesting to know how many RV ers have had to replace white vent covers/lids etc. due to deterioration due to the effects of UV.

[Dogpatch]

I'm gonna paint mine green so they match my "eyes" LOL. That ought to get some people going!

[Southernboy]

My ac covers , vents etc are black i kinda like the look

You must have one weird looking MH if your tank is mounted on the roof
