1991 International Background Info
The 1991 International Vibe
Welcome to 1991, the year Nirvana's Nevermind was on every radio and the International Navistar 4700 was the undisputed king of the job site. Back then, these trucks weren't "lifestyle vehicles"-they were tools. While the car world was experimenting with neon teals and magentas, International stuck to the colors that actually meant business. Our database highlights the survivor that defined the era: Beige. It's the ultimate "get it done" shade, designed to hide a layer of job-site dust while looking professional in the rearview mirror of a project manager's sedan.
Paint Health Check
We are firmly in the Peeling Era. By 1991, the factory was moving toward basecoat/clearcoat systems to get that high-gloss finish, but the chemistry hadn't quite mastered the art of "sticking" yet. If your International has been sitting under the sun, you're likely dealing with delamination. It starts as a small bubble or a cloudy patch on the hood or the roof-what we call "sun-scald"-and before you know it, the clear coat is flaking off in sheets like a bad sunburn. Once that clear lifts, the beige pigment underneath is defenseless against the elements and will turn chalky in a matter of months.
Restoration Tip
When dealing with a 1991 clear coat failure, speed is your best friend. If you catch a chip or a small area where the clear is just starting to lift at the edges, seal it immediately. Clean the area thoroughly with a solvent-based prep to remove any old wax, then use a high-solids touch-up to "bridge" the gap between the healthy paint and the peeling edge. This prevents air and moisture from getting under the clear and traveling down the panel. If the clear is already flaking, don't just paint over the flakes; you have to carefully sand back the "shelf" of the peeling clear until you hit a solid edge, or your new repair will just lift away with the old failure.
