Is there a temperature range for application of the Deep Gloss spray sealant, i.e. can a surface be too cold or hot? I'm convinced that frequent application of an lsp spray is key to protecting the clear coat.
I wouldn't apply it to a hot surface. Especially a dark color car/suv that has been sitting in the sun for a while. I always let my vehicles sit in the shade, or garage and cool before I apply any products.
