Black bumpers, plastic and trim can become damaged from UV rays, rain, grime, oxidation and even strong car wash soap. However, by using a car trim restorer, you can permanently restore the defective plastics back to black.

How We Rated The Trim Restorers

After years of detailing cars, we have tried and tested plenty of plastic trim restorers and only very few produced excellent results. In terms of rating the plastic trim restorers within this article, we based our recommendations upon our own experience of using multiple branded products as well as a number of factors. The factors that we considered included their type, ease of application, durability, surface compatibility and value for money.

Plastic Trim Restorer Buying Guide

Using a plastic restorer will allow you to transform faded trim or bumpers back to black. Due to UV rays, rain, dirt and other environmental factors, most plastics eventually begin to fade. Without any suitable protection, fading will occur far quicker than you would expect.

There is a whole range of plastic restorers available but choosing the best can be tricky. However, you should always ensure that you don’t use a black dye on plastics that aren’t dark colored as this may have adverse effects.

To help you make an informed buying decision, we have produced the below guide regarding trim restorers.

What Causes Plastic Trim to Fade

The main cause of plastic fading or cracking is due to environmental factors and general driving such as UV rays, rain, road grime and other dirt.

Poorly washing your car can also speed up the damaging effects. For example, many people will use too strong of a car wash soap, which can strip the finish of the plastic trim.

Methods To Restore Black Plastic Trim

  • Restoring using detailing products
  • Using peanut butter or an oily substance
  • Using heat to bring out the oils
  • Painting the defective plastic

The most trusted and best method to restore faded car plastic is to use “off the shelf” detailing products such as the products listed above.

Using peanut butter to restore faded plastic is a popular method but not necessarily the best. The oil in the peanut butter provides the restoring effects but at the same time makes a mess and produces a strong smell.

Using a heat gun to heat up the trim can bring out the oils in the plastic. However, all plastics are different and only so much oil can be taken from the plastic. It would also be best to test on a hidden piece of plastic before you attempt visible areas.

The final option would be to simply paint the plastic trim. The plastic may be past restoring and this would be a permanent fix. Alternatively, you could plasti dip the plastic trim or even use automotive vinyl wrap to cover up any defects.

Once you’ve applied a plastic trim restorer, you would expect the finish to be long lasting. Although there is no truly permanent fix, many premium options can last up to 2 years or longer. Although the longer lasting restorers are more expensive, they will reduce the amount of applications required per year.

To further increase its durability, there are many unique ceramic coatings that are suitable for plastic trim. The coating provides unbeatable protection and may be a great addition for maximum protection.

Silicone Based Formulas

Some black trim restorers claim that they don’t contain silicone within their formula. The benefits of a silicone-free plastic restorer is that it usually produces a non-gloss finish that’s long lasting. Silicone based formulas are known for becoming stripped by strong car wash soaps or rain, which means they require regular topping up.

Gloss vs Shiny Wet Finish

Some brands provide different levels of restoration when it comes to their plastic restorers. For example, the Meguiar’s Back To Black provide a shiny wet finish whereas the Gtechniq C4 doesn’t effect the gloss level whatsoever. It’s worth noting that products that provide a shine often require regular topping up to maintain the shine upon the plastic.

Faded black bumpers, plastic and trim on your car not only ruins the appearance but also devalues the car when it comes to resale. Fortunately, a trim restorer is relatively easy to apply and any of the recommendations above will restore the plastic back to black.

To avoid disappointment, we advise that you purchase a large quantity of the product so that you can restore all of the exterior plastic trim that has faded. There is nothing worse than running out of the product halfway through the restoration.
