Dear cyclops,

Hope you're well. A "primer" paint is that put on an underlying surface, e.g., directly onto wood or metal, to seal the underlying surface and to provide a base to which further coatings can bond. Thus, atop a "primer" are put coatings that provide color and protection to the underlying surface. A "clear coat" may go atop the colored coatings, to seal the colored coatings.

Thus, if the clear coat is peeling, a skilled painter can remove the failed clearcoat - by careful sanding - apply coatings to refresh the color, and then top-off with a clear-coat. This is time- and labor-intensive so not cheap. But it will do as much as can be done to restore the factory-original coatings.

Sanding down to bare metal should be avoided. The steel used in 940s is heavily-coated with zinc, which inhibits rust. Sanding to bare metal will remove that protective zinc coating.

Hope this helps.

Yours faithfully,

Spook
