1. 3M 03614 – Molding Tape Plastic Glue for Car
Editor's Rating: (4 / 5)
If you are looking for a molding tape type of plastic glue, then this 03614 from 3M should be your go-to option. The tape is very high quality and features a super strong adhesive that is widely known to be present in 3M products, which is a well-known brand in this segment.
With a width of half an inch and a length of 15 feet, this piece has the strong adhesive on both sides, and can withstand all weather and high impact, making it ideal for attaching trims, side moldings and even emblems permanently to either car interiors or exteriors.
However, before installation, thorough wiping is required on the surface so as to remove any wax or silicone, and 3M cleaners are recommended for this job.
On the plus side, when doing the installation, the tape can be easily cut to size so as to fit the required length of the component being attached to the car, and can also be removed mess-free if you mistakenly placed it wrongly on the car’s surface.
2. J-B Weld 50139 – Quick Setting Plastic Glue for Car
Editor's Rating: (4 / 5)
This 50139 from J-B Weld is the top-rated plastic glue for cars in this review, and with its features, it is easy to see why.
For starters, the glue sets very quickly in as little as 15 minutes to form a black filling that can be sanded in as little as 30 minutes. That said, it comes as a 2-part glue, consisting of body panel urethane adhesive and gap filler which combined, create a very strong bond that rivals steel.
This bond is strong enough for doing repairs on thermoplastics, carbon fiber, composite plastics, and even concrete, but you must ensure that the two are mixed in the ratio of 1:1 for the best result.
Other features are the inclusion of two built-in application syringes, one for the adhesive and the other for the filler, and a resealable no-waste cap for locking in the remaining glue.
On the downside, the glue comes in a very small quantity of 25ml and should be handled with care since it is very poisonous.
3. Amazing GOOP 160012 – Good Plastic Glue for Car
Editor's Rating: (4.3 / 5)
In addition to being a plastic adhesive, Amazing GOOP’s 160012 doubles up as a sealant that can be used to seal leaks in hoses, as well as eliminate vibrations in screw connections so as to reduce noise and improve the effectiveness of screws in joints.
As an adhesive, this plastic glue is very effective at repairing a number of things, such as vinyl tears on floor mats, car seats, and convertible tops.
In addition to this, the glue can bond to metal, glass, leather and other materials, and can actually be used to protect battery terminals from corrosion, seal headlight and windshield joints, stick emblems and molding strips and also act as an insulator in electrical wiring.
When used in all these, the adhesive creates a flexible bond that is waterproof and paintable. However, it is flammable with a harmful vapor and therefore, should be handled with care.
4. 3M 38808 – Aerosol Plastic Glue for Car
Editor's Rating: (4.1 / 5)
3M’s 38808 is a highly versatile plastic glue that is designed to bond strongly to heavy automotive materials such as metal, foam, fabrics and of course, plastic.
However, what stands out most about this product is that it is packed in an aerosol can, which is very effective at dispersing a controlled amount of adhesive so as to form an even layer on surfaces, leading to clean bonds with no excess adhesive sticking out.
Even though the formula dries up in 30 minutes to 1 hour, which is a long time, it is recommended for carpets, headliners and other fabrics because, in the end, it creates a strong bond especially between them and non-porous surfaces such as metal and plastic.
Additionally, it does not stain the fabric and resists the damaging effects of heat, cold, humidity and other conditions for durability purposes.
5. Pratley 5864264843 – Best Glue for Plastic Car Part
Editor's Rating: (4 / 5)
This product stands out as one the best plastic car glue because it comes as a complete kit containing a 20ml acrylic adhesive and two 15ml powder fillers, one in black and the other in white.
With this, you can use the adhesive on its own for attaching emblems, rubber trims, wheel caps and other plastic parts to the car, or combined with the fillers for covering up cracks on bumpers, dashboards and the like.
Since you get black and white fillers, you can fill black and white surfaces, or even grey ones because all you have to do is mix a small portion of the fillers to come up with a grey color.
Once applied, a strong heavy-duty joint is created that can be filed, sanded and painted after setting, and is heat resistant up to 90°C (194°F).
However, the remaining acrylic glue should be kept refrigerated after use so that it remains fresh for the next repair.
6. U-Pol 0727 – Waterproof Plastic Glue for Car
Editor's Rating: (4.2 / 5)
U-Pol’s 0727 is also a 2-in-1 adhesive plus sealant product, which dries up to create a permanent waterproof seal that is very durable.
It comes packed in a relatively large 310ml cartridge tube, and this gives you enough sealant for covering multiple leaking points around your car’s windows.
As an adhesive, the product creates permanent bonds between trims and body panels and once cured, it can be painted over using any car paint so as to hide the joint.
For easy application, a threaded funnel is included, which allows you to screw it into the tube opening so that you can direct and apply the glue to the exact place where it is required.
On the downside, the adhesive dries up to form a black seal, which might not be ideal for a white or brightly colored surfaces. However, you can paint over it once it's dry to your preferred color.
How to Buy the Best Plastic Glue for Car
#1. Permanent or Semi-Permanent
There are two main types of glue for plastic car parts.
Permanent plastic glue is used to attach or repair components that you have no plans of removing at all throughout the lifespan of the car. For instance, when repairing a bumper, permanent glue is better because the section needs to remain attached and in one piece throughout.
This type of glue is ideal for fitting in parts that might be changed later. For instance, double-sided tapes are good for fitting in trims and spoilers and can be easily removed later on without messing up the underlying paint job if you want to change these parts.
#2. Your Purpose
Another important factor to consider is your intended purpose. If you intend to fill up cracks and holes on your car, then you need to buy a glue/sealant or better yet, a plastic glue pack that comprises of the adhesive plus powder fillers.
There are also certain varieties, for instance, 3M’s 38808, that are more suitable for attaching fabrics to non-porous surfaces such as plastic, and these would be ideal for repairing seats, top covers and the like.
However, for attaching regular plastic parts to the car, all the products above will work and thus, you can pick whichever you want.
This is a no brainer. A waterproof plastic glue for cars is definitely better to buy because it will create a durable seal that maintains its integrity even in humid conditions, which are very common, especially if used on a car’s exterior.
#4. Ease of Use
This has mostly to do with the glue’s packaging in which, certain features such as the syringes in J-B Weld’s 50139 make it easy to dispense the liquid glue and filler onto the required surface.
Another convenient packaging mechanism is the aerosol can type of glue. This makes it very easy to dispense glue in small amounts for better control over the application process.
There are many other features that simplify the application process such as funnels, and you should consider such so that you have an easier time doing the repairs or fitting.
As you can see, gluing parts to the car or carrying out repairs is actually a very simple process if the right glue is used and when used properly.
With all these considerations, you should have an easier time picking the best plastic glue for cars after going through the plastic glue for car review above.
