One of the unique things about the product is that it is very easy to use, very clean and it won’t run down the sides of the trailer. It dries to a smooth beautiful finish. On a metal roof it will quiet the roof and reduce the heat in the interior. It is very easy to make spot repairs on metal roofs and an excellent product to seal vents and pipes. I use, at this time no other sealant. If a customer wants a roof with a less expensive product that is not as reliable, I refuse to do the job.
