Please, please please do not use any more of the "devil's own goop"!
Somehow silicon (silly-cone) manages to combine a couple of "interesting" attributes. It will not stick worth a (censored) to fiberglass, yet it is impossible to get off! On fiberglass it does not prevent leaks
, yet anything applied OVER it (or where it used to be) won't work properly either!
It is difficult to remove, cannot be painted over and has very few redeeming qualities (and that's just the good points!!!
However, it will likely last for the upcoming season.
For any further caulking you may want to do, please - for the sake of your own future sanity - use any kind of other caulk except silly-cone.
There are many threads on this forum about the many sealers and caulks, with general consensus being that butyl rubber is the very best, with Dicor being not too bad.
