B) Self-etching primer

Answer:

After using a phosphoric acid-based cleaner on bare metal, a wash primer is used to improve adhesion and provide corrosion protection.

After using a phosphoric acid-based cleaner to prep bare metal, the next step is to use a wash primer. A wash primer is a type of primer that is designed to improve the adhesion of subsequent coatings to the metal surface. It also provides a barrier against corrosion.

Other options listed, such as self-etching primer and phosphoric acid-based conditioner, may also be used in certain situations, but wash primer is the most commonly used after a phosphoric acid-based cleaner.

Epoxy primer is another type of primer that is used in some cases, particularly when there is a need for added durability and corrosion resistance.
