How to Buy Best Plastic Glues for Car Parts

How To Buy Best Plastic Glues For Car Parts
How To Buy Best Plastic Glues For Car Parts

1. Permanent or Semi-Permanent

As you choose plastic glue, you often need to decide the type that you want. Here, this typically means picking between the permanent and semi-permanent types.

The permanent glues will provide a stronger bond between the pieces, and they are ideal for repairing things like bumpers and trims that require more hold power. Note that such glues are built to last, and so in case you change your mind about using them, you will have a hard time removing it from the surface.

With the semi-permanent glues, you get a more temporary solution. But, these glues still form a strong enough bond to hold the pieces together. They are also easier to remove when you want to without leaving any messy residue on the surface.

2. Material You Want to Apply

Given the different chemical compositions and ingredients used to make plastic glue, they adhere to varying surface types. Hence, the best glue for automotive plastic for you should be ideal for use on the specific material you want to repair.

Most of these glues will be suitable for plastic materials, which should be good enough, as this is the most common material in many vehicle interior and exterior. However, some like the J-B Weld 50139 are more versatile as they can adhere to other materials like coated metal, fiberglass, and even ceramic.

3. Need to Drill or Sand

In some instances, you may need to drill or sand over the glue once cured. Hence, when choosing your plastic glue, it is vital to make sure what you buy leaves a finish that can be sanded and is drillable.

The adhesives that act as a filler will be preferable in such cases as they make it possible to restore the surface to your desires appearance by drilling or sanding.

4. Quantity

The quantity of the glue in the tube or container also matters a lot as it determines whether you get good value for money or enough product to finish your intended repairs.

But given that these are heavy-duty glues with strong bonding capability, a little of it will be more than enough for most jobs.

Typically most products provide as little as 0.5 fluid ounces of glue, which is more than enough, but you can still get high volume ones like the 18.1-fluid ounce 3M 38808.

5. Shelf Life

Because you will not always use all the glue in the tube or container, it is essential to check the shelf life to ensure that you can keep any leftover glue until you need to use it again.

Luckily most can last for many months when you store them properly. You need to be careful when handling them because many dry out if you leave them open and allow air to get into the tube.

6. Durability

Any plastic glue that you choose needs to be durable to ensure you do not need to keep reapplying it now and then. Durability becomes even more critical when you have to use the glue on exterior surfaces that are at the mercy of the elements.

A good plastic glue should resist water and sun rays as they are some of the most common elements the repaired section will encounter. Also, it should be tough enough to withstand typical vibrations that emanate from the vehicle's engine.

7. Color

If you are applying the plastic glue on an exterior surface, color-matching is vital to ensure it will not look out of place.

For example, a black glue weld on a red bumper leaves an unsightly look that can make the vehicle look older than it is, and so in such cases, you are better off sticking with something transparent.

Glues that set to black color or tan will often come with more work for you as, in most instances, you need to paint over them to maintain the vehicle's aesthetic appeal.

8. Time to Set

The time the glue takes to set also matters a lot as it determines how long you need to wait before driving the vehicle or doing other jobs like sanding or painting the surface.

Here a fast-setting glue like the Gorilla Micro Precise 102177 that sets in as little as 10 seconds will be super convenient as it means you hardly have to wait for the adhesive to set. But, those that set in 5 minutes, like most others on our list, are still good enough.

Frequently asked questions

Can I Use Plastic Glue on Other Materials?

A: Yes, but this often depends on the specific plastic glue type or model you are using. Besides plastic, most of these glues adhere to other materials like fiberglass, PV, coated metals, and aluminum, which are the typical material in the vehicle's interior and exterior surfaces.

How Long is the Shelf Life of Automatic Glue?

A: Shelf life varies significantly from one brand of glue to the other, but most typically have a shelf life of between 6 and 12 months. But, some brands can last up to 24 months. Also, note that the shelf life decreases once you open the tube.

Conclusion

With the best plastic glue for car parts, you have an effective solution for repairing trims, moldings, and many other car components.

From our review above, it is clear there is a plastic glue for you regardless of the material you want to repair. However, the J-B Weld 50139 is our best overall as it provides superior tensile strength and will bond to almost any surface.
