Can anyone comment on the use and quality of rust reformer coatings? I have an iron porch railing that is much decayed where the posts enter into the concrete landing and steps (posts 75-100% gone). I would like to get a few more years out of the whole thing before needing to replace. I need to spread out my larger home renovation and repair costs for tax reasons.
I is so difficult to get rid of 100% of the rust without renting a sand blaster. I'd like to wire brush it off and coat with something that will not just bubble up right away.
I am looking at Loctite Extend rust treatment. They would like to see a coat of "high build epoxies", coal tar epoxies, catalyzed urethanes, vinyls, chlorinated rubber" before coating with latex. Do you chemists out there see any problem with this? How about suggestions for the barrier coating?
Thanks for reading.
