Some vehicles are prone to rusty window and door channels like 70's muscle cars, square-body or OBS trucks with their multitude of pockets, corners, and channels that love to hold water and moisture to create rusty problems. But the good news is that you can do some of that rust repair on your own.

Door frames: a complex system of curves, corners, and pockets – all of which love to hold as much moisture for as long as possible. You’ll not only want to stop the rusting process in those problem areas but seal the metal, too.

Window channels: These channels are runways that trap water between the glass and aging, dried-out rubber. And they do a great job of hiding the resulting rust until it is too late to prevent damage.

Roofs and rockers: the top and bottom of your car or truck can take a lot of beating from the elements. Small and medium-sized holes in your roof or rocker panels, created by rust, are problems you can solve with these products.

We’ve combined our most popular rust repair and prevention kit and utility products into one easy-to-use window and door seal repair bundle, designed to attack the common rust problems.
