I've decided to apply kool seal to my aluminum roof but am confused as to which "formula". On this site, most just refer to it generically as "kool seal". However, on their web site, there are different variations including one that is more specifically labeled for aluminum and some that are not, but are listed as good for aluminum. The specific one includes some type of fiber. Also, recommended, is a base layer. So I am confused. Is there a general product and approach folks like to use? Is the base layer necessary for my (our) applications or just a way for the mfg to talk me into buying more product? Any and all suggestions appreciated.
