Typically once you use silicone sealant on something you are stuck with it. Its almost impossible to remove all of the residue from silicone sealer. There are some different grades of silicone sealant. You might look for an acid cure sealant. You wont find that at your local home depot or hardware store. You would have to look at a commercial sealant supplier. I know Dow Corning makes it. reseal the wheels and let it cure for about a week before you put pressure on it.
