If it comes with that silver already on it, then you're at the mercy of what the paint is. You can layer it for more insulation value.
If it's not silver already, then see what paint will reflect the most, both for sun (visible) and heat. If you can get a very shinny aluminum paint, then it may actually have aluminum particles as pigment instead of colourized mica pigments. The aluminum particles would likely be the best bet for reflecting the most heat away possible.
I'm having no luck finding the rattle-cans I found before, nor any specs for the ones I do find. (I should have saved that info, but was assuming I'd get updated info when I needed it...)
The problem with an aluminum or silver paint is, what pigments did they use and how reflective is it, both for sunlight and for heat (infra-red). Without knowing, you'd be taking a gamble with how well it will perform.
But, you could use White Krylon Paint:
- Will not reflect away as much heat as a paint designed to, or using pigments that, reflect heat away.
- Will reflect away more visible light and heat than a "looks like" aluminum paint, which is using darker-than-white pigments to fake the look of aluminum/silver.
- Gloss White reflects slightly more.
- Will certainly perform much better than not coating the blue bubble wrap, just not as well as foil-sided bubble-wrap or the aluminized mylar space/emergency blankets.
and let us know after how well what you end up with worked on-playa.
