What is a potential downside of sandblasting?

Sandblasting is a method used to remove paint, rust, and other contaminants from surfaces, but it has its drawbacks. One significant downside is that it may cause overheating of panels. The intense force and friction generated during the sandblasting process can lead to a rise in temperature, which can warp or damage thin metal panels. This overheating can affect the integrity of the material, especially if it is aluminum or other heat-sensitive substrates.

Understanding this potential damage is essential, as it highlights the need for careful consideration and technique during the sandblasting process, such as monitoring the time spent on each area and possibly using cooling methods to mitigate overheating effects. Other options in the question may not accurately represent common issues associated with sandblasting, making the acknowledgment of overheating a key aspect of assessing the risks of this method.
