Silicone oil seems fine for Hypalon
In fact silicone is used extensively in the rubber and plastic moulding business as a mould release agent.
I have used both Armourall and 303 - there seems to be no difference to me except price.
I have a very old inflatable dinghy(circa1970) which is made from hypalon and doesn't seem to have suffered from having armourall sprayed all over it!!!
I bought a gallon of 303 at a silly price - yes it makes the RIB look nice but you have to apply it at least once a month - usually more often. I am going to use the floor sealer next!!!
I suspect 303 are great at putting out scare stories to make their product "essential".................
