Will Shot blasting Remove Chrome?
If you would like to remove chrome from your vehicle, shot blasting is not the easiest route. Based on small areas, it could easily take 12 to 16 hours for just one wheel in a blast cabinet. One big problem that comes with shot blasting chrome, aside from it taking forever, is that it is very difficult to tell when you’ve reached through the other side.
The metal plating takes on a matte silver colour as soon as the grit blasts it, and when you get past that the only change you may see is when sparks stop coming off the surface as it is blasted.
Shot blasting chrome on top of aluminium can be a risk, as aluminium is softer than chrome. If you open up a blister or an edge is the plating, the sand will begin to dig a hole in that area before the chrome surrounding it will come off, and you may be left with wavy wheels.
Generally, shotblasting can be more trouble than it’s worth when it comes to removing chrome. If you have the patience, mask any areas you wish to save with a wood or metal mask that will take a heavy blasting, and then blast with coarse sand at a high pressure. This should shatter the brittle chrome. However, you are leaving your vehicle vulnerable to more damage than if you were to remove chrome another way.
A good way to remove chrome from your vehicle would be to take them to a plater who is able to remove the chrome and the underlying plating by reversing the plating process. If you are not interested in having them rechromed, you could opt for having them power coating once the chrome is removed. For something like this, you wouldn’t necessarily have to use a shop that does decorative chrome work, an industrial plater would do the job just as well.
Shot blasting is best kept for removing paint, rust and other eyesores from your vehicle, allowing you to paint, polish or otherwise to make it look as good as new without weakening the metal underlays. If you would like to know how Rye Metal Finishing can help you, please feel free to contact us.
