Pre-Paint/Conversion Coatings

Rust is the Problem.

Blasting creates profile.
It doesn’t stop flash rust.

If parts sit unprotected between blast and coat, oxidation begins immediately — compromising adhesion before powder ever hits the surface.

See how improved post-blast pretreatment stabilized the surface and improved coating performance. Read the case study.
