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 will eventually begin to fade. Without any protection, fading will occur far quicker than you would expect.

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

To help you make an informed buying decision, we have produced the below comprehensive 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 solution, which can strip the finish of the plastic trim.

Methods To Restore Black Plastic Trim

There are four methods to restore faded plastic back to black, with each having their own benefits, which 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 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 effect but at the same time makes a big mess as well as resulting in 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 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. You could also plasti dip the plastic trim or even use automotive vinyl wrap to cover up any defects.

Durability

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.

Silicone Based Formulas

Some black trim restorer products 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 is 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 will provide different levels of results 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 products that provide a shine will often require regular topping up to maintain the shine upon the plastic.
