The joint surface preparation standards by NACE International and the Society for Protective Coatings (SSPC), which have recently united to form The Association for Materials Protection and Performance (AAMP), are widely accepted among contractors and organizations.

To aid comprehension, the following is a simplified breakdown of each standard.

Shot peening is a controlled process used to finish metal parts to prevent fatigue and stress corrosion failures. Shot peening also helps prolong a product's lifespan.
