Common Mistakes When Using Flap Discs and How to Avoid Them

Flap discs are awesome tools that make surfaces nice and shiny. But a lot of people mess up when using them. Let’s talk about these mistakes and how to avoid them, so you can rock flap discs!

Choose a grit that is too coarse, and you might hurt the material you are working with. If the grit is too fine, you might not achieve the amount of smoothness you desire. For best results, you want to match the grit to your task. Keep in mind, the higher the number the finer the grit!
