Rubber roof caulk

My rubber roof caulk is cracked and I had a few waters leaks. I don't want to recaulk the entire roof. I'm considering applying liquid rubber roof over all the lap caulking. How do you feel about that and has anyone else done that? Is ther another way besides recaulking? I did fix the leak with epdm caulk.

    It is the only thing that stopped my skylight leak. It goes on like paint.

    Cover the seams and edges with Eternabond. Caulk where you can't use Eternabond.
    Don't waste your time/money using liquid roof to replace caulk.

    2oldman is correct. Heng's is good stuff.

    I think you are wasting your time and money. If you've recaulked the cracks in the existing, then you're good to go.
