Silicone on an RV is the devil! It degrades relatively quickly when exposed to UV and weather. It's especially devilish characteristic is that it will loose the adhesive bond and still stay intact, looking like it is still sealing.

You can then remove it with a rag. Wipe down the area with solvent, mineral spirits or acetone. Then, apply a polymer based sealant. Geocel 2300 is the type I now use. It is a sibling of Proflex RV.
You don't have to believe the silicone cautions. Prove it to yourself. Apply some beads to some metal and lay the metal out in your back yard. Watch it for deterioration.
