How to Paint Over Chrome Plastic

The best way to approach the process of painting chrome is thorough and methodical. When preparing your surface, you do not want to be creating an uneven surface as this will compromise the integrity and durability of your project in the long run. It is best to do the job properly the first time so that you are not disappointed and disheartened.

Cleaning the Chrome

When you are painting something, it is usually necessary to put in a bit of time and effort to prepare the surface you would like to paint on, otherwise the paint will not adhere and you will be sorely disappointed. In the case of chrome, this is where most of the work is involved.

Prior to paint, chroming parts will be mounted on the jig and they are then cleaned with Isopropyl Alcohol.

Frequently Asked Questions

How to Paint Over ABS Bright Chrome?

The first thing you need to do when painting chrome, is to clean the surface. Next, you have to sand the surface evenly and thoroughly to get rid of any bubbles and to remove any of the thin, clear rust that may have accumulated since chrome reacts with the oxygen that it is exposed to. If you leave this shiny layer on the item you are wanting to paint, it exposes your paint job to the possibility of peeling sooner rather than later.

Can you Paint Over Chrome Plating Plastic Auto Parts?

It is possible to paint chrome electroplating plastic automotive products, but it is not guaranteed that the paint will stick. Painting the plastic plating parts requires a lot of surface preparation before you apply the paint, including cleaning, sanding, and applying primer. As an alternative to painting your ABS plating parts, you can buy a proper plastic that you can paint. This may be slightly more expensive, but is a much easier and quicker option as you will not have to do as much surface preparation, not to mention that paint will adhere better to a plastic surface.

How to Prepare Chrome for Painting?

Because chrome reacts with oxygen to form rust, you will have to, in the first place, clean your surface to remove any dirt and grime. Do this with a damp cloth. You will then have to sand it with rough sandpaper, such as 120-grit sandpaper. Wipe the surface down again, then use 240-grit and finally 320-grit sandpaper to remove any scratches or marks the heavier sandpaper has made. The goal is to produce the smoothest and most even surface possible. Wipe your surface with a damp cloth again. Finally, paint with a primer and allow to dry.
