AC Auto is a top local provider of rust prevention undercoating, helping protect vehicles from the corrosion caused by harsh New England weather. Road salt eats frames, brake lines and fuel lines from underneath; a proper undercoat is the cheapest protection you can buy for a vehicle you plan to keep.
Why undercoat
Winter road salt and spring moisture attack the underbody first: the frame, floor pans, suspension mounts and the brake and fuel lines you cannot see. Undercoating seals those surfaces before the rust starts, or stops it spreading on a vehicle that already has some.
Done on the lift, done properly
The vehicle goes up on the lift, the underbody is cleaned and prepared, and the coating is applied to the frame, floor, wheel wells and exposed lines. It is one of the services our customers mention most in their reviews.
