I announced a few days ago that Castaloy, a cast iron repair rod, was offering free castaloy to anyone that posts on the castaloy forum and likes the castaloy facebook page.  I will be having a meeting next week to finalize a decision to allow customers that have already purchased Castaloy to select one of the other two products; steelaloy or alumaloy.   I plan to announce on the alumaloy forum within the next couple of weeks a contest to win free aluminum repair rods so check back.  😀
