I have used this product on my boats for sealing under deck plates, hooks, etc... with great success. It was recommended to me for sealing horizontal seams on my RV by a local RV dealer. With my past success I thought it would be the ticket. Plus, UV is in the name, so it should be great... not so much. All of the seams I sealed last year failed. After one year in the sun, the sealant turned ashy and started coming out of every place I put it. The previous sealant I used was simply a home exterior window caulking and it lasted for ten years. Truthfully, the old home caulk was still serviceable but had attracted a lot of dirt so looked ratty.For applications that do not see the sunlight or just occasional sunlight, this product works well and is easy to use. However, if your boat or RV sees constant sunlight, it will fail in short order.
