I apologise if I use the wrong terminology but I was wondering if anyone has experience with replacing the "sealant"? around the helm area that attaches to side of the hull of the boat?
It just looks like bathroom sealant but I would imagine is more resilient to sea water and marine grade?
Mine is starting to get a little black in a few places and would like to clean it up to make everything look nice and new again

Is there a procedure to replace or can it be cleaned with a product?
