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.

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

Methods To Restore Black Plastic Trim

There is four methods to restore faded plastic back to new, each with their own benefits, they include:

  • 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 by using “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 effect but at the same time makes a big mess and 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 plastic. It would be best to test on a hidden piece of plastic first before you attempting 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. You could also plasti dip the plastic trim or even use automotive vinyl wrap to cover up the defects.

Not having to constantly apply the product to the faded plastic car parts is highly desirable. However, they are not a truly permanent fix and overtime they will begin to fade once more.

Some trim restorers may only last a few weeks whereas premium products can last one or two years. The long lasting examples will come with a premium price tag but it’s worth spending the extra.

Silicone Based Formulas

Some black trim restorer products claim to not include silicon whatsoever. The benefits of a silicone-free plastic restorer is that it will usually produce a non-gloss finish that is long lasting.

Silicone formulas are known for becoming stripped by car wash soap or rain, which means you will be required to top it up on a regular basis.

Gloss vs Shiny Wet Finish

Some brands will provide different levels of finishes when it comes to the plastic restorer products. 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 product that provide a shine will often require regular topping up regularly to maintain the shine.

What Are Your Thoughts?

  1. The interior plastic on my just purchased 2013 Honda CRV is dark brown and not black. What can i use? There are scuffs and scratches which I really want to restore.

    The exterior plastic is either very dark grey or black so I think a black product would be ok?


  2. I own a yellow Kawasaki Tryx UTV and the yellow plastic is has dulled through the heat of the sun. Can you recommend something I can use to bring back the luster and shine? Thanks
