An orbital sander with a scotch brite pad was used to lightly abrade the surface, which was too thin to achieve an ideal preparation. The surface was cleaned with MEK. A heavy coat of Belzona 2121 was applied, the barrel was wrapped with Belzona 9331 and a second heavy coat of Belzona 2121 was applied.
