There are many kinds of rubber roof sealants. It appears that the on marketed for RV are more expensive. Which one do you use (most cost effective) . Thanks

I'm a fan of Dicor, but I would use whatever your manufacturer suggests.

If it is the top of the roof I wouldn't use anything except Dicor self
leveling.

I'm assuming you're talking about roof coating and not caulking?
For caulking, Dicor self leveling is a good choice.
For coating, HENG'S Rubber Roof Coating is what I use. It goes on easily like paint, it's cost is lower and it needs no primer. It looks good and holds up well.

I put two coats on our 96 Southwind, 2 1/2 gallons for 30' of roof.
I'll use Heng's again.

Ditto.

But, if cost wasn't a factor, I'd take it to a truck bed liner guy. Rhino Liner and Line-X would last 50 years.

Go to Home Depot and get Henry's 887 silicon roofing. Look it up under Henry's roofing too. Its made for RV'S too.

I have used the Dicor acrylic sealant on two different units over the last 10 years. It functions well and last for a time. I now own a 4 yr old Class C and just recently recoated the top (rubber roof) with the Henry's Tropicool 100% silicon. I can say it does a phenomenal job. It adheres extremely well to the surface and looks like a brand new roof. It is said to be much better than the acrylic material that Dicor sells which last in my case only 2-3yrs at best. I added two coats of the Tropicool silicon and it makes a tough and smooth finish to the rubber membrane. Don't think you can go wrong with this one. Not so expensive if purchased in the 5 gal size but also available in the 1 gal as well from Home Depot and many others. Check the Youtube site for RV coating.
