Dicor RP-IRC-1 CoolCoat Roof Coating - 1 Gallon https://www.amazon.com/dp/B00B2ATAWQ/ref=cm_sw_r_awd_d-vawbC9HF5W0
Thanks Brad. You mean for MG's poptop roof for my roof.
This Dicor looks like a good option. The only other product I had been suggested by another ExPo member so far was http://www.tempcoat.com/temp-coat-products/temp-coat-101/prod_2.html
If using a brush or roller, then this variation; http://www.tempcoat.com/temp-coat-products/insulall/prod_4.html
From the ExPo member; "I found Temp Coat while researching coatings for an "RV Box" that I am building with a friend. I spoke with the owner's son, Jason, who is very nice and very knowledgeable about the product. He suggested an interior or an exterior coating depending on aesthetics, as the product does finish a bit on the matte side. You could easily spray the interior sheet metal, then cover it up and spray the roof sheet metal inside and out or even a double layer on the exterior. A single layer is about 30 mils, which is about the thickness of a credit card and that layer will give the equivalent of an R-20 in heat reflectivity and insulation against conductive heat transfer into your van. We are looking at it for a composite box type structure and it will be an exterior coating for us.
The product is 60% elastomeric, but is not designed to be a bridging product, so that would be another advantage of spraying it on a relatively flat exterior metal, versus the inside where you have all the support ribs and such. It may simply just take more product if you spray the inside for that reason.
We also considered a Lizard Skin heat control product, but I feel the Temp Coat is better for our application. With composite panels for the walls and ceilings, we should be about an R-30, due to the components of the composite structure. You may wish to consider a spray foam as a vapour barrier and to help seal off all of the small spaces that batting or foam board can't cover."
