About spot repair

What is denibbing?

In vehicle manufacturing and refinishing, after a coat of paint or clearcoat has been applied, there is a chance that small imperfections such as dust nibs have become embedded in the surface. With careful sanding and polishing of the spot in question, the surface imperfection can be erased, without the need to refinish the entire panel. 

Why is abrasive quality important? 

Every sanding step should make the following step easier. With a consistent scratch pattern, the sanded spot is far easier to polish out, making it impossible to see where the imperfection once was.

What is the benefit of using cordless tools? 

When performing detail work, keeping the cord of a power tool away from a freshly finished surface can be a distraction. With a cordless tool, you are free to focus on the job at hand, making it easier to get the best possible finish.
