What Is Auto Sealer? Definition, Meaning and Concept

Auto Sealant consists of a group of products formulated to enhance, seal and protect automotive paint work from the elements. Also known as paint sealants, these products are synthetic polymers that not only adhere but form a lasting bond with the paint job. Auto sealant products serve the same purpose as car wax, but generally offer longer periods of protection. They are also faster and easier to apply than traditional wax finishes. Self-sealing products can also offer some protection from minor scratches and chips.


Exposure to ultraviolet (UV) radiation in sunlight, rain and humidity, dust, insects and bird droppings can wreak havoc on fine automotive paint finishes. If left unprotected, the paint on cars exposed to the elements will eventually develop blemishes and fade to the extent that a second paint job is necessary. Regular applications of a good auto sealer can prevent this undesirable and costly situation from occurring. These products are easy to apply, long lasting and enhance the beauty of the car.


Many car enthusiasts believe that car sealants are superior to traditional natural car waxes. Natural wax finishes are generally based on carnauba wax; While they impart a warm, rich shine to a car's paint, they don't last very long. They also tend to leave a white residue on the plastic trim that can be difficult to remove. Auto sealants, on the other hand, are synthetic polymers that actually bond with the paint, thus creating a hard, long-lasting protective layer. This layer protects against UV exposure, sheds water, and protects against acid rain, spills, and acid in bird droppings.


Due to the bond formed by the auto sealant with the paint, these finishes can last up to six months. The best products can even last a year or more before a new application is necessary. Most conventional wax finishes are only good for six to eight weeks, so auto sealers are cheaper in that regard. Many sealers are also tough enough to protect the paint from minor scratches, scuffs, and stone chips.


Auto sealant products are best applied to a clinically clean, dry paint surface. Before applying the sealant, the car should be thoroughly washed to remove all traces of dust and grime. The paint should be blotted dry to create a streak free surface. Once dry, the auto sealer is applied according to the manufacturer's instructions. Most of these products impart a brilliant shine and other details are usually not necessary. The finish must be monitored over time; When the water no longer forms beads on the paint, the sealer should be reapplied.
