It's a well known thing out there. especially with car guys that once you use Armorall on rubber items, you will need to keep using it regularly or it will actually hasten the rubber's aging and perishing if you stop. I can attest to this as it happened to a Honda Automobile I owned in the 80's. Every thing was fine for a then I went through a short period when didn't get to use it and all the rubber based trim around the windows started drying out really fast and cracking. I quit using it on my cars after that experience and I did not have the same problems anymore. I would not use it if I were you, or if you do want to use some preservative/protector product, try to avoid Armorall if you can.Anyway, I would question ausing anything silicone based, slippery fluid like there are in many protectants on a tire where you want maximum traction for safety.
