Corrosionpedia Explains Bittiness

Bittiness gives an otherwise smooth metal surface a rough and uneven appearance. It is also known as peppery when the trapped solid particulates under the coating are small, seed-like and widely dispersed.

Bittiness is often caused by improper cleaning of the metal substrate surface prior to coating application. It may also be a primary cause of crevice corrosion due to moisture confinement. Proper surface cleaning is an ideal preventative measure.
