Is that a problem to replace it with silicone after old removal?
Vulkem or any other sealer, except silicone, will not adhere properly to silicone.
The answer however is easy.
Totally remove ALL
the silicone trases chemically.
Then and only then will the Vulkem adhere properly to a surface.
Simply rermoving what the eye can see of old silicone, is not enough.
Hardware stores sell silicone removers in spray cans, that can be used to solve the issue.
