1. J-B Weld 50139 Plastic Bonder Body Panel Adhesive
- Brand: J-B Weld
- Manufacturer: J-B Weld
The J-B Weld 50139 Plastic Bonder is a high-performance urethane adhesive system designed for heavy-duty automotive repairs. Its quick-setting formula, with a 15-minute work time and a full cure in just 30 minutes, makes it a standout for users who need fast results. With a tensile strength of 3770 PSI, this adhesive is perfect for repairing thermoplastics, carbon fiber composites, and even coated metals. It dries to a durable black finish, making it ideal for visible repairs on plastic bumpers and body panels.
In testing, the J-B Weld 50139 excelled in bonding strength and versatility. It adhered seamlessly to a variety of materials, including PVC and fiberglass. The self-mixing syringe design simplified application, ensuring a consistent 1:1 mix ratio. However, its quick setting time requires users to work efficiently, which may not be ideal for beginners. Additionally, while the black color is excellent for certain repairs, it may not match all surfaces, necessitating additional painting for aesthetic consistency.
Pros
- High tensile strength (3770 PSI) for durable repairs
- Quick setting and curing time
- Self-mixing syringe for ease of use
- Versatile across multiple materials
- Dries to a professional black finish

2. J-B Weld AutoWeld
- Brand: J-B Weld
- Manufacturer: J-B Weld
The J-B Weld AutoWeld is a specialized adhesive designed for automotive applications, offering impact resistance and a strong bond. With a similar 15-minute set time and 30-minute sandable cure time as the 50139 model, AutoWeld is ideal for repairing bumpers, dashboards, and even body panels. Its included static mixer ensures a hassle-free application process, making it user-friendly for both professionals and DIYers.
During testing, AutoWeld demonstrated impressive durability, with no shrinkage over time, which ensures a long-lasting repair. Its compatibility with fiberglass, metal, and rubber makes it a versatile option for various car components. However, the lack of a specific price point and limited availability in some regions may make it harder to source. Additionally, while it performs well on most surfaces, it may not adhere as effectively to certain textured plastics.
Pros
- Impact-resistant and durable bond
- Static mixer for easy application
- Fast curing time
- Versatile for multiple automotive applications
- No shrinkage over time
Cons
- Limited availability in some regions

3. Gorilla Original Gorilla Glue
- Brand: Gorilla
- Manufacturer: Gorilla
Gorilla Glue is a household name, and its Original formula offers a polyurethane-based adhesive that expands into materials for a strong, waterproof bond. While not specifically designed for automotive use, its versatility makes it a potential option for car bumper repairs. It bonds wood, metal, ceramic, and more, making it a multipurpose solution for various repair needs.
In practice, Gorilla Glue provided a reliable bond on rigid surfaces like metal and concrete, but its expanding nature required careful application to avoid overfilling gaps. The curing process is slower compared to other adhesives on this list, taking up to 24 hours for a full cure. This, combined with its brown color, makes it less suited for visible bumper repairs. However, for non-cosmetic fixes or general-purpose use, it’s a strong contender.
Pros
- Extremely versatile for various materials
- Waterproof and temperature-resistant
- Forms a strong, durable bond
- Ideal for non-cosmetic repairs
Cons
- Expands during curing, requiring precise application
- Brown color unsuitable for visible repairs
- Longer curing time compared to competitors
4. Amazing GOOP 160012 Automotive Adhesive – 3.7 fl. oz.
- Brand: Amazing GOOP
- Manufacturer: Amazing GOOP
Amazing GOOP 160012 is a multipurpose automotive adhesive that excels in versatility. It’s designed for a wide range of automotive applications, including sealing leaks, insulating electrical wiring, and repairing vinyl tears. Its waterproof formula ensures durability in both indoor and outdoor conditions, making it a reliable choice for car bumper repairs and more.
While GOOP impressed with its ability to bond diverse materials such as vinyl, plastic, and metal, its 24-hour curing time may test the patience of users looking for a quick fix. Additionally, the adhesive’s viscosity made it slightly harder to work with compared to syringe-based products. However, its ability to protect against corrosion and its vibration-proof properties make it a valuable tool for comprehensive automotive maintenance.
Pros
- Highly versatile for various automotive applications
- Waterproof and corrosion-resistant
- Bonds well to vinyl, plastic, and metal
- Durable and vibration-proof
Cons
- Longer curing time (24 hours)
- Thicker viscosity can be challenging to apply
5. J-B Weld 50133 Plastic Bonder Structural Adhesive Syringe – Tan – 25 ml
- Brand: J-B Weld
- Manufacturer: J-B Weld
The J-B Weld 50133 Plastic Bonder is a budget-friendly option that doesn’t compromise on quality. Featuring the same 15-minute set time and 3770 PSI tensile strength as its premium counterpart, this adhesive is ideal for DIY plastic repairs, including bumpers, dents, and more. The tan finish makes it less noticeable on lighter-colored surfaces, adding to its versatility.
In our tests, the 50133 delivered consistent results, adhering well to thermoplastics, composites, and coated metals. The resealable syringe design allowed for multiple uses, making it cost-effective. However, the 30-hour full cure time is significantly longer than the premium 50139 model, which may deter users needing faster repairs. Additionally, the tan color may not blend well with darker surfaces without additional finishing.
Pros
- Affordable price without sacrificing quality
- High tensile strength (3770 PSI)
- Resealable syringe for multiple uses
- Versatile for various materials
- Tan color suitable for lighter surfaces
Cons
- Longer full cure time (30 hours)
