How do you know if a car has been Teflon waxed?

To determine if a car has been Teflon waxed, look for a smooth, glossy finish on the paint that repels water, causing it to bead up rather than spread out. You can also perform a simple test by rubbing your hand over the surface; if it feels slick and has a slippery texture, it may have been treated with Teflon wax. Additionally, you might notice that dirt and grime do not adhere as easily, making the car easier to clean. Checking for product application receipts or asking the owner can also provide confirmation.
