In this video, I will be showing you how to polish faded paint on a trailer. Beyond trailers, this can also be used on other glossy painted surface, this will even work on a vehicle’s paint. I’m still slowly cleaning up this trailer, while it is hard to see, the white paint is mildly scuffed and oxidized. This method can be used on a variety of painted surfaced, it’s not intended to remove all surface imperfection, but it’ll certainly be an improvement.

It’s important to wash the trailer, removing any dirt on the surface which can cause issues during the polishing process such as additional scratches. If the trailer is important and you’re looking for a top-quality shine, then I’d recommend using a clay bar too. However, I won’t be getting into that for this trailer.

Once it’s dry, using a polisher, here I have a rotary style, an orbital style can be used as well. With a rotary style, there is more chance of burning through the paint, so you need to be mindful of that.

This trailer has aluminum painted panels and I believe this is a single-stage paint, meaning there is no clear coat. I’m using a polishing compound, there are various manufacturers on the market available. The one I’m using can be purchased at your local auto parts or big box stores. As for a pad, this is a light polishing foam pad. These are typically color-coded and vary between manufacturers.

Apply the polish to the pad, typically I would recommend dabs across the pad. Watch for any sling when starting the polisher, you can drag or dab the pad across the surface to prevent this.

As you can see there is a small scuff, this method can be used to remove that along with oxidation, improving the shine of the paint.

Only apply light to medium pressure, work across the surface. Don’t hold the polisher in one spot as it can burn through the paint. Then follow up with a soft cloth to remove the leftover polish.

While it is harder to see on white, there is still a noticeable difference in the surface clarity.

After that, I can work section by section. Extra care is needed around the fasteners, panel edges, and decals so take your time. This trailer is from 2006 and all original, so the paint seems to have held up well over the years and it most likely didn’t see any maintenance as what a car’s paint may experience.

When done, the paint is now bare so you can finish up with a wax or sealant to protect the surface. Here I have carnauba wax, I’m using whatever I had laying around. This will protect the paint and help repel dirt.

Use a microfiber pad to apply the wax to the paint. Allow it to haze over, this takes about 15min but can vary between products and weather conditions.

Then give it a final polishing using a microfiber cloth.

If you have any lights, trim pieces, or other items you don’t want the wax to come in contact with, you can tape off those areas.

And here is the final finish.
