How do you folks tell if its Dicor or a similar product.
I've used nothing but Dicor on my '97 31' 10" trailer. The last time I had any issues was in 2008 when the OEM sealant cracked a bit around one side of the skylite. Simply worked it loose with a putty knife and added self leveling Dicor. looks like OEM. The trailer has never leaked.
Eternabond laying around the roof on all the fixtures/roof jacks/etc looks like bandaids which affects resale and has even caused one trailer owner to loose his new trailer roof warranty.
If you go with Eternabond work it down per instructions and add Dicor (or similar brand self leveling sealant) around the edges like the pros and like the jplante4 picture.
Great stuff for its intended use but is not a permenant fix like some say.
