Dinitrol Penetrant LT Cavity Protection Spray - 2 X 500ml Cans, Beige/Transparent, For Rust Prevention & Cavity Sealing

If you're into preserving your car, truck, or project vehicle, you know the name Dinitrol.

This is a set of two 500ml cans of Dinitrol Penetrant LT.

It's a cavity protection product, designed to seep into seams and hollow sections to stop rust before it starts.

Brand new, made by Dinol.

The color is beige, but it dries to a transparent waxy film.

It's perfect for inside frame rails, doors, rocker panels—anywhere moisture likes to hide and cause trouble.

The LT stands for Low Temperature, so it's formulated to flow well even in cooler conditions.

Part number is 1147004001_2.

It's a cavity sealing wax that creeps into those hard-to-reach spots and forms a protective barrier.

If you're restoring a classic or just want to keep your daily driver from turning into a rust bucket, this is the stuff to use.

Two cans give you enough to do a good portion of a car.
