Looking for opinions on non-asphalt-based sealants that are UV stable.
I have seen polyurethane, butyl, acrylic and silicone.
(1) Which of these formulations do you think is best?
(2) Please suggest a brand that is readily available at Ace,
Tru-Value, Home Depot or Lowes because I will need it soon. I would
prefer not to have a black color.
Your help is very much appreciated.
Thank you.
Frank
