Your car’s topcoat is what gives it its glossy, clean finished look. When taking a car polish to the surface of your auto body, you want to keep in mind that the topcoat is particularly sensitive to the abrasiveness of the polish and must therefore be applied with a gentle hand. This is because, once the topcoat is gone, you can’t go back without the assistance of a professional technician. You may think that without the topcoat, you’ll be able to see a glossier finish due to the car polish, but be aware that this comes at the expense of the depth and clarity of your car’s paint job which can result in a patch of paint that doesn’t match the rest of the body. So, do yourself a favor and be very careful to save and protect your topcoat when polishing your car and thank us for it later.
