Resealing hatch caulking

I have to reseal areas on several access hatches and ports on my aluminum sided travel trailer (Vertical / horizontal caulking). No leaks yet but being pro-active. I have always been told that you were not to use any silicone product to do this BUT.. this is what my local RV Repair store uses and is recommending I use. It is made by BOSS products.. (Boss 378) Any comments or opinions before I start on this project?

    Obviously not on the rubber roof though.

    Me and some of you guys are not going to live long enough to see the quality silicone deteriorate. :h


    Silicon on the exterior will peel right off.

    Before using your caulk leave the tube in the sun or heat with a heat gun.

    Dicor and a bowl of soapy water. If you dip your finger in the water and use it to smooth the joint you'll get better results.

    I would not. Dicor or Proflex are the accepted options. I have tried Proflex and hated working with it. So Im only using Dicor now.
