Adding custom lettering to your truck’s tailgate, grille, or hood is one of the easiest ways to add a custom touch. But just because it is easy does not mean they all are the same or do the same job. This first Not all letter inserts are made from the same material, and that difference affects everything from appearance and durability to long-term value.
The three most common materials are vinyl, plastic, and stainless steel. Each has its own strengths depending on your budget, how you use your truck, and how long you expect your upgrades to last.
Does Material Really Matter?
The best material depends on how you use your truck and how long you expect your accessories to last.
If you’re looking for an affordable way to personalize your vehicle or plan to change its appearance every few years, vinyl or plastic inserts may be all you need. However, if your truck is exposed to road salt, harsh weather, automatic car washes, job sites, or off-road conditions, investing in a more durable material can pay off over time.
While appearance is often the first thing buyers notice, factors like UV resistance, corrosion protection, scratch resistance, and long-term durability become increasingly important the longer you own your truck. Choosing the right material now can help your letter inserts maintain their appearance for years with minimal maintenance.
Vinyl Letter Inserts
Vinyl decals are the most affordable option and are widely available for many trucks. They apply like a large sticker, making installation simple and inexpensive.
Pros
– Lowest upfront cost
– Wide variety of colors and graphics
– Easy DIY installation
– Great for temporary styling
Cons
– Can fade from prolonged UV exposure
– More susceptible to peeling over time
– Vulnerable to scratches from washing or off-road use
– May require replacement after several years
Best for: Budget-conscious owners, leased vehicles, or anyone wanting a quick cosmetic upgrade.
Plastic Letter Inserts
Plastic inserts are a step above vinyl and typically use molded ABS plastic with painted or coated finishes. They create a more substantial, three-dimensional appearance than flat decals.
Pros
– Raised OEM-style appearance
– Better impact resistance than vinyl
– Available in multiple finishes
– Moderate price point
Cons
– Painted finishes can chip over time
– Lower-quality plastics may become brittle after years of UV exposure
– Some finishes can lose their original appearance with heavy use
Best for: Daily drivers looking for a factory-inspired appearance without moving into premium materials.
Stainless Steel Letter Inserts
Stainless steel inserts are designed for long-term durability and a premium appearance. Rather than relying on painted plastic or decals, they’re made from corrosion-resistant metal that resists everyday wear while providing a more refined look.
Premium stainless steel inserts often feature advanced finishes such as brushed stainless, polished stainless, or specialized black coatings that bond directly to the metal instead of simply covering it.
Pros
– Exceptional corrosion resistance
– Won’t rust like ordinary steel
– Excellent resistance to fading and weather
– More resistant to scratches and everyday wear
– Premium fit and finish
– Designed to last the life of the vehicle
Cons
– Higher initial investment
– Heavier than plastic or vinyl (though insignificant once installed)
Best for: Truck owners who want a long-lasting upgrade with a premium appearance.

Which Material Is Right for You?
Choose vinyl if you’re looking for the lowest-cost way to personalize your truck or want the flexibility to change styles later.
Choose plastic if you want a raised factory-style appearance at a moderate price point.
Choose stainless steel if you want a permanent upgrade that delivers premium looks, excellent corrosion resistance, and long-term durability with minimal maintenance.
Frequently Asked Questions
What material lasts the longest for truck letter inserts?
Stainless steel lasts the longest due to its resistance to corrosion, UV exposure, and everyday wear. It is designed for long-term durability compared to vinyl or plastic.
Do vinyl or ABS plastic tailgate letters last longer?
ABS plastic letters last significantly longer than vinyl decals. While premium vinyl typically lasts 3 to 5 years before shrinking, fading, or cracking, ABS plastic inserts are more resistant to UV damage and harsh weather and can often last the lifetime of the truck.
Can you put a pressure washer directly over vinyl tailgate inserts?
You should avoid spraying high-pressure water directly at the edges of vinyl inserts, as it can lift the adhesive. ABS plastic or stainless steel inserts mounted with automotive-grade 3M tape handle pressure washing better, though maintaining a safe distance is still recommended.
Will matte black vinyl tailgate letters fade in the sun?
Standard matte black vinyl can fade or degrade under prolonged UV exposure. Cast vinyl materials (such as 3M 2080 or Avery Dennison films) include better UV stabilizers and are significantly more resistant to fading than calendared vinyl.
What is the difference between vinyl and 3D domed tailgate letters?
Vinyl letters are flat adhesive decals that sit flush on the surface. 3D domed letters use a raised base (typically plastic) with a clear epoxy dome layer, creating a raised, glossy, dimensional appearance.
Do stainless steel tailgate letter inserts rust in winter?
High-quality stainless steel inserts made from T-304 stainless steel will not rust, even in winter road salt conditions. Lower-grade or unbranded metals may corrode, discolor, or pit over time in harsh environments.
Are acrylic or ABS plastic truck letters better for extreme heat?
ABS plastic is better suited for extreme temperature changes. Acrylic can become brittle under thermal stress, while automotive-grade ABS maintains strength and flexibility in both hot and cold climates.
How do you remove baked-on vinyl letters without damaging paint?
Apply heat using a heat gun or hair dryer to soften the vinyl, then peel it slowly using a plastic scraper. Any remaining adhesive can be removed with an automotive-safe adhesive remover such as 3M Citrus Base Cleaner or Goo Gone Automotive.
Is 3M adhesive tape safe for factory truck clear coats?
Yes, genuine 3M automotive-grade acrylic foam tape is safe for factory paint and clear coats. It creates a strong bond while still allowing clean removal with heat and adhesive remover when needed.
Can I install stainless steel letter inserts over existing vinyl decals?
No, existing vinyl decals and adhesive residue must be fully removed before installation. Stainless steel and ABS plastic inserts require direct contact with a clean factory paint surface to ensure proper adhesion.
