Rust is one of the worst things that could happen to your vehicle. It might start small but can spread fast without proper treatment and car rust repair. If you want to avoid corrosion like a pro, the first thing to do is address any signs of rusting immediately instead of waiting it out. That way, you can prevent further issues, and your car can stay road-worthy and aesthetically pleasing for much longer.

How can I prevent rust?

Choose automotive paints that passed extensive independent scientific testing to prove their efficacy and longevity and with official US patents for their advanced technologies of providing superior protection and outstanding adhesion. Ensure it is easy to apply and requires minimal to no surface preparation.

What makes the best automotive paint?

Choose an automotive paint for car rust repair that contains more metal and is thinner than industrial corrosion inhibitors for ease of application with a roller, brush, or HVLP automotive finishing gun. Verify that the formulation is versatile for all applications, including floor pans, undercarriages, suspension, rocker panels, and frames. The best product can be used as a standalone coating, primer, or with other potent rust inhibitors for better protection.

Ensure best results

Coat the surface of your vehicle with a high-build sandable primer before applying the automotive rust inhibitor paint. Always follow the manufacturer’s recommendations for proper application. Wait at least 24 hours for the coating to dry and scuff with 150 grit before applying primer.

Don’t forget the undercoat.

Pros apply undercoating as part of car rust repair for outstanding protection against abrasives and corrosives. However, some rust inhibitors are versatile and can serve the same purpose.

Use the right applicator.

Depending on the rust inhibitor you’ll use, consider HVLP spray equipment with a 1.7 to 2.0 tip and 40 to 60 psi or 1.5 to 1.7 tip and 40 to 60 psi. It should achieve a dry film thickness of around 1.5 to 2.0 mils per coat. Don’t forget to clean the sprayer, equipment, and any filter after the car rust repair.
