I have an aluminum Jon boat painted with the traditional Olive Green.
The painted surfaces get extremely hot to the touch in the hot,
afternoon sunlight. Is there a paint available for metal surfaces that
stays cool to the touch in direct sunlight? Thanks, Mike Howard

Now there's a great idea, something like the "Cool Deck" they put around
swimming pools. It's probably out there somewhere.

Cool Deck involves mixing a lot of lightweight puffy rock dust into the
plaster. It's probably not flexible enough for an aluminum boat. The idea
is that while it gets as hot as any other surface in the Arizona sun, it
conducts heat so poorly that it won't blister you feet like ordinary
concrete does.

"Puffy rock dust"?

Sounds like fumed silica.

Yeah, maybe. I can't remember (from 1967) but it comes from really old
volcanoes.

Two approaches come to mind:
1) paint white or silver to reduce absorption
or
2) cover with thermal insulation
You might consider a trailer/roof coating. This is thick and white
and might do the job well. There are also apparently custom coats
specially formulated for insulation.

Brian Whatcott Altus OK

when you think about it, you are painting paint not aluminum (mostly),

why not just paint it a lighter color, prep the existing paint and give it a
go with a durable marine paint.
