Are you team rot……. Or team Not?
Undercoatings are becoming popular around here. Knocked a few out today.
Ohio roads are hard on vehicles. Salt and brine get into seams, frame rails, and cavities and start rusting from the inside out. So we don’t do a single spray. We use three Dinitrol products, each for a different job.
Step 1: Dinitrol ML
A thin, penetrating rust inhibitor. It creeps into seams, pinch welds, and tight spots, pushes out moisture, and stops rust that’s already starting.
Step 2: Dinitrol 4010 (clear ish)
A thicker wax we use inside frame rails, doors, rocker panels, and other hidden cavities. It sticks, stays flexible, and seals over the ML so moisture and salt can’t get back in. We also use this in a brand new vehicle scenario where we don’t need black.
Step 3: Dinitrol 4941 (black)
A tough underbody coating for wheel wells and exposed areas underneath. It stands up to road spray, gravel, and salt, and it cuts down road noise too.
Each layer handles something the others can’t: getting in deep, sealing it up, and taking the hits.
New or used, the sooner it’s protected, the better. Message us or call to get on the schedule before winter.
