Yes, it aint done till it's done.
Vinegar-smelling silicones are not entirely safe to use for encapsulating bare & operating electronics/conductors (acid), but I expect the LED strip to be somewhat insulated - even a layer of varnish will do. After it sets it's completely safe anyway though.
Silicone is incredibly tough & reliable as a glue, & if you use too much of it you'll regret it the day you might have to remove what you put up.
