I would NOT.
Do not use silicone, which is probably dissolved in petroleum distillates, or baby oil, which is.... oil. They're both bad for rubber.
Use what you can buy. The type of silicone dressings found in most vinyl/rubber protectants and tire dressings are the only type you should be using. Try to avoid the clear, colourless stuff if you can.
I don't know how thickly you glop your tire dressing on, but it takes me an awful
long time to go through even one bottle of tire gel.
I bought an armload of tire dressing on clearance last year and bottle #1 is still going.... Even those big cans of No Touch seem to last a while for what they cost.
