Been using it for 40 years with out a problem. To each his own.Never use silicone on your camper! In the future if any caulking repairs are required, nothing will stick to the existing silicone or to what the silicone was adhered to.
I recommend OSI Quad, you can get it at any DYI home repair store. Stuff is a bit messy to use. Tape the area you do not want it on. Apply a very small amount. With a super soapy water finger and smooth. You can add more OSI Quad as you work it.
