Crack in roof sealant

[NCFischers]

I know this has been discussed before but I need some info. What is the sealant that is used on the roof when sealing penetrations and where can I get it? I found a small crack in the sealant around the antenna.

I use Dicor self=leveling caulk.

Orv has the right product, Dicor from an rv store. Clean the area. I find if you cam put a V cut in the old sealant not to deep, you will get a better seal.

I use the same stuff, works great. old turbo is right about cutting a V and filling it with the caulk. I wound up removing most of the factory stuff from around my antenna because I could see where water and dirt had gotten under some of it. Be carefull when cutting the old stuff, the rubber roof doesn't like sharp objects .
