painting the roof

[JohnEd]

Ed,

Looks good!  What are you doing for AC?

Bill,

I am insympathy with you.  My bus, when I get it, will be white with maybe some light accents.  Did you foam the roof and sides in your bus?

Thanks,

John

Nice pictures everyone.  My ex-schoolie Crown also has a white roof.  Has anyone done any scientific testing to see what happens when radiant sunlight hits the roof of a vehicle?  I know white or light colors are supposed to "reflect" the sunlight, but does it really work defeating the "infrared" part of sunlight that is supposed to be responsible for the "heat"?  I dunno which is why I am asking.  Sweating during the summer and Crowns Forever and all that stuff.

I don't have any tests...but there is a good reason why most dark colored buses leave the factory with white roofs....becuase it reduces the load on the A/C

Cautions:

Adding sand or using rubber like paints on the roof will casue dirt to accumulate up there....then when it rains that dirt will run down the sides of your bus.

Also using cheap paint........it will chalk and do the same....you will have attractive white vertical accents on your bus after rains

We did a test several years ago.  South Florida, mid July, about 3 PM. 2 buses sitting in the sun. Our bus is mostly ultra white with a few fire engine red stripes. The west side of our bus was white 113 degrees, Red 126 degrees. The other bus was dark metallic green with mauve and gold metallic stripes. Dark green was 146 degrees, Mauve was 123 degrees ans gold metalllic was 126 degrees. What ever temperature the metal is, that is the heat that is being transferred to the inside of the bus.  All temperatures were measured using an infrared laser temperature gun.  Jack

John,

This MCI-9 was complete when I purchased it last Oct.  The best I can tell it has an inch or so on installation.  Which is not enough... Not with two overhead A/C's.  I passed four Prevost this morning on I-10 in Florida that had four overheads each.  Guessing they were entertainers.  Two where pulling matching trailers.

I stop by Fred's in North Florida a couple weeks ago.  You should see how it does the spray form.  Really started my mind working.  Thanks for the tour Fred.

Here's the link,  I have the beads in the clear coat on my roof.  

my bus needs a bath from being under a tree.

I have 2 13,500  btu's and rarely need more than one,  and hardly ever both on high.

next time I might use their elastomeric mix with their clearkote.

I used Kool Seal on roof down to the gutter rail. Makes a big differance on interior temps.

When I paint the bus I intend to paint it white with color accents somehow.

Has anyone painted over Kool Seal or is there to much movement with temp. changes?
