What type of compound contains mineral abrasives to clean and prepare a panel for finishing?

The type of compound that contains mineral abrasives used to clean and prepare a panel for finishing is a sand fix compound. These compounds are formulated specifically to enhance the surface of materials before applying further coatings, which is crucial for ensuring good adhesion and a smooth finish. The mineral abrasives within these compounds help to remove imperfections, such as scratches or oxidation, and create a surface that is ready for the next stages of the refinishing process.

Polishing compounds, while useful for refining surfaces and bringing out a shine after finishing, do not typically contain abrasive materials aimed at preparing a panel. Instead, they are more suited for final touch-ups. Base coat compounds are applied as the initial layer of paint on a surface, and topcoat compounds serve as the outer protective layer, neither of which are designed specifically with abrasives for preparation.
