Never had a problem with the new silicone sticking to the old silicone.
It wasn't until about 6-7 years ago that I started using Dicor, after I found out(?) from numerous forums that silicone shouldn't/couldn't/wouldn't/WON'T work, the RV will leak like crazy if it comes anywhere near silicone, especially the next time time you try to add silicone, not to mention that you will NEVER get all of it off in order to seal it RIGHT (with Dicor)!
Sorry, but that just hasn't been my experience. And it seems that I usually had fewer areas to touch up each year when I was using silicone that I have using Dicor. So I have to wonder why we are all convinced that Dicor is the holy grail of RV sealants? :h
