I have a cement heat sink of a south and west facing wall and have seen these new exterior paints with reflective metal flakes suspended in the paint and they claim to be highly reflective [and expensive].

Anyone out there have experience with this product?? Does it really work??

is it too good to be true??

Thanks in advance for info before I buy.

are they available in Thailand?

They have been advertised here so expect that they are available. I don't recall the specific brands but it was more than one.

Seems I've seen them in Homepro and other big hardware shops and at least a couple of the major brands now carry their own formulation, but they are pricey and that's why I want to hear from satisfied users before I buy.
