small roof leak fix?

I discovered after the last heavy rain I have a minor roof leak - I keep the RV stored under a roof and have never used it in the rain believe it or not ( It's a new unit built in 2016 ). Yeah I guess I could go hassle with the dealer but would rather try something myself as they are not that convenient to me. I have identified the leak and it is where water pools by a seam. I have an aluminum roof and the standard looking roof goop/caulking they use. Is there a method to add new caulking to the existing? or some other method besides removing the entire seam of caulking and starting over?

    We also have an aluminum roof and have done Eternabond on all seams, front and rear cap and around all vents/ac etc. Do proper preparation to surfaces and you won't have to worry about it again.

    X2. Eternabond, if applied correctly, is usually a one time repair.

    There's a very good chance it's Dicor self-leveling lap joint sealant that they used from the factory. If so (it's kind of like used chewing gum consistency when cured), you can touch it up by cleaning the area thoroughly and putting a bit more on top.

    It would be wise to check all the caulked seams and cutouts and edges while you're at it and deal with any that show signs of cracking (more than slight surface cracking, at least) or pulling away or otherwise have issues. This is a typical once or twice a year maintenance item.
