10 Best Automotive Primers 2025 in the United States

The Dupli-Color EBPR00310 Gray Perfect Match Scratch Filler Primer is an acrylic lacquer aerosol primer designed for easy use on both metal and plastic surfaces. One of its main strengths is its quick drying time, with the product becoming dry to the touch in just 30 minutes and fully curing in 6 hours. This makes it very convenient for users who need to complete their tasks quickly. The primer is also sandable, which helps in achieving a smooth surface before applying the topcoat.

The adjustable EZ Touch 360-degree nozzle and wide spray pattern ensure smooth, even coats, further enhancing the ease of application. It is specially formulated to fill scratches and provide a smooth base for topcoating, making it suitable for repairing chipped, scratched, or damaged surfaces before applying the final paint layer. However, it does not seem to offer specific corrosion resistance, which could be a drawback for projects involving metal surfaces exposed to harsh conditions. Additionally, while it is not water-resistant, it does offer a glossy finish that can be beneficial for aesthetic purposes.

For those looking to repair and prepare surfaces quickly and efficiently with a smooth finish, this primer is a solid choice, especially for projects primarily focused on aesthetic repairs rather than corrosion protection.

The Krylon Black Fusion All-In-One Spray Paint is a convenient option for those looking to combine primer and paint in one step. Its 5X stronger adhesion and rust-resistant formula make it suitable for metal surfaces, including automotive parts, providing good corrosion protection. It dries quickly with full curing in about 20 minutes, allowing for faster project completion. The satin finish is attractive and waterproof, making it durable for both indoor and outdoor use. Another plus is that it requires no sanding or separate priming, which can save time and effort during prep work. The spray can with its big button tip allows for easy application from different angles, which is helpful for detailed or hard-to-reach areas.

As a combined paint and primer, it might not offer the same level of sandability or smoothness as dedicated automotive primers, which could be a drawback if you need a highly refined finish before applying a topcoat. While it works well with various surfaces, some professional auto body users might prefer specialized primers designed specifically for automotive painting processes. This product is best suited for hobbyists or DIYers who want a quick, all-in-one solution for minor repairs or projects rather than heavy automotive refinishing.

The Krylon 12 oz K05584007 White COLORmaxx Paint & Primer Spray Paint is a versatile product that combines both paint and primer in one can. This type of primer is convenient for those who need a quick and efficient solution for various surfaces including metal, wood, plastic, wicker, fabric, and glass. It dries relatively quickly, with a full cure time of 24 hours, which is quite standard. The rust-resistant feature is particularly beneficial for metal surfaces, providing an added layer of corrosion resistance that is crucial for automotive applications.

The primer also offers good adhesion and durability, making it a reliable choice for both indoor and outdoor projects. The easy-push, big-button tip is user-friendly and allows for application in any direction, even upside down, which adds to its versatility. However, it is noted that the product is not water-resistant, which could be a limitation in certain environments.

Additionally, some may find the coverage area of 25 square feet per can to be limited, potentially requiring multiple cans for larger projects. The sandability aspect is not explicitly mentioned, but given its multi-surface compatibility, it can be inferred that it performs adequately in this regard. This primer is a solid choice for those looking for a convenient spray application with good rust protection and multi-surface compatibility.
