Which recoating product to use

Ok so some people are saying do not use silicone to coat the camper roof and around the vents. I was looking at the Henry products because someone told me it works great, but the product that the Henry people suggested was the 887 which is 100% silicone, another roofing product they have is 100% acrylic, can someone help me to get the right product to re-coat the roof and seal around the vents, with hopefully the same stuff
Thanks

    I use Dicor sealant, it is the same stuff the factories use and what is compatable with the Dicor rubber roof that is on the majority of the RV's.

    Absolutely not. Why would you not use readily available self leveling lap sealant that's specifically made for this purpose? :@

    Because I need a coating that will be either brushed on or rolled on to cover a bigger surface than the lap sealant is able to do

    Look at EPDM coatings. They get good reviews and there are a lot of self help and DIY videos on the product.

    Since Dicor - and I guess others - make roll on coatings SPECIFICALLY for use on EPDM roofs, why would you screw around with something else that probably won't work as well, and may well fail for you causing even more problems?

    I use this stuff regularly: Heng's Rubber roof coating

    Had a leaky skylight that only that product generously applied worked.

    I used Liquid Roof on mine 4 years ago and it's held up great. I use Dicor's self-leveling lap sealant for touch ups around vents and other protrusions through the roof.

    Henry's 887 Tropic Cool is a non-solvent silicone coating. I used it on my last RV using a brush and roller, 2 coats. It looked great and was cool to touch in sunlight. Rv felt cooler inside. I will be using it on my new 5th wheel soon.
