09 Rockwood Roo roof sealant

I have a 2009 Rockwood Roo and need some advice on roof sealant. I think I have the TPO roof. I need to seal some of the joints on the roof before I have issues. What type of sealant should I use ?

I have used the dicor before. Wanted the beige stuff that FR used on the camper. It appeared way more pliable than the Dicor. CW had this Alpha Systems product in the color needed and it appears to be the same consistency as FR used after it set up and cured

Forest River uses the Alpha Systems sealant on the TPO roof. (the TPO roof membrane is made by ALpha)
They sent me a tube of Alpha 1021 in beige.

Dicor makes a good EDPM product and I'd bet it would work OK on the TPO but the wording on their website made me seek out what the factory uses...
Dicor's Self-leveling Sealant is a high solids, gun consistency material designed to be used in conjuntion with single-ply EPDM Membrane and some TPO Roofing.

The word 'some' was enough for me to request what the factory uses.

Evergreen used to use Dicor on their TPO roofs so that's what I have been using. No issues. I just need to get some that's will hold its bead to correct a drainage issue around a skylight.

I've used both Dicor 501 and Alpha Systems TPO lap sealants on TPO roofs. I can't tell the difference.

Dicor says their 501 lap sealant will work on "most TPO roofs" and it seemed to on my 2010 Roo, but they do make a self-leveling lap sealant specifically for TPO roofs. Their standard lap sealant is 501 in a green tube but they also have a product called ultra-sealant in a blue tube. The ultra sealant also comes with a primer but it may not be needed if you're touching up existing cracked sealant.

Be careful . Read the tube of Dicor, it states not for use on some TPO roofing . It will bubble up the TPO.

After sealing the roof I used eternabond tape over the Dicor to extend the life of the sealant.
