Touch up nicks sooner rather than later
Touch-up paint won’t adhere well to rust. So be sure to keep some matching touch-up paint on hand so you can touch up any minor nicks, often found around door edges, before rust has a chance to form.

Protect car paint from the sun
Paint does more than make your vehicle look great. It’s also the first line of defense against rusted body panels. Of course, the best way to protect the paint is to park the car in a garage. If that is not possible, park in the shade or purchase a car cover. The sun’s ultraviolet rays break down paint and cause it to fade. Some car covers protect your car from more than sun, moisture, bird droppings, and dust — they also have a thin layer of cushioning that will guard against light impact, such as from a tipped bicycle or small falling tree branch.
Place a towel under baby seats
All manner of food bits and liquids can accumulate under a baby seat, where they can permanently stain the upholstery. Place a sheet of heavy plastic and an absorbent towel under the seat to prevent damage, and re-secure the seat according to the manufacturer’s directions.

Keep leather from drying out and cracking
Leather cars seats are durable and don’t require a lot of maintenance. After a few years, however, the seats can become soiled. Use a leather cleaner to remove dirt and stains.Then apply a leather protectant formulated for pigmented or top-coated grain leather (the leather used for most leather car upholstery). Protectants will resist stains and make the upholstery easier to clean in the future. Choose a protectant that includes conditioners to keep your leather supple.
