Charliehorse, I moved your post out of the ask the factory. This is a pretty simple project and you can use any 100% silicone product. I've re-caulked ours and used clear silicone with good results. The important part is the prep and removal of the old sealant. Make sure you get all the old sealant off and clean the area good with alcohol and make sure the surfaces are DRY before the new sealant goes down.
