Application Method:

The substrate was prepared via media blast with Black Beauty, cleaned, taped, and then conditioned with Belzona 2911. Once cured for ½ hour, a two-coat reinforced system of Belzona 2131 was utilized to create a polymer overlay over all assembly seams/joint. Bolt holes and other protrusions were top-dressed with a coating of Belzona 2131.
