Silicone sealant is a great caulking, but it's limited in its applicant. Primer and paint will not adhere to silicone sealant. If you paint over silicone caulking the paint will crack and fail. Nothing will stick to cured silicone sealant, including other caulking and silicone caulking itself. When silicone sealant is cured or it fails, it's very difficult to remove. If you want to prime and paint or apply new caulking in an area where silicone caulking has been applied, you have to remove every bit of the silicone sealant or nothing will adhere to the area where silicone sealant has been applied.
