A quick look at their website doesn't appear that it is recommended for RV's.
What type roof do you have ?

What you do NOT want to use is silicone caulking.

Most on here use Eternabond tape to do the seams. Roof Leak Repair Products & Sealing Tape | EternaBond®
Some 3M 4200 or 3M 5200 but if you do the 5200 just be sure you really don't want to try to get it off later as it really does stick on. 3M Products Superstore - Industrial General Store
We went with Teakdecking SIS-440 caulking The World's Leader in Pre-Manufactured Custom Teak Decks - Teakdecking Systems®
Some use Dicor https://dicorproducts.com/catalog/roof-products/

While the Solar 900 specs don't mention RVs, the general applications listed include fiberglass and metal joints, so that aspect should be fine. As for roof seams, it would depend on the roof material. If you have an EPDM or TPO roof, I would recommend a sealant designed for compatibility with those materials. If a fiberglass or metal roof, the Solar 900 should be ok.

As an alternative, try Geocel Proflex RV. It too is a tri-poymer sealant (the technology that Solar 900 claims) and it is specifically rated for most RV applications. And it is widely available as well.
