    I need to seal a leak in an extractor. Anyone know of a food grade caulk that would work in a galvanized tank?

    Why not use RTV? Just let it cure long enough for the vapors to evaporate. I don't know if it is food grade or not, but I wouldn't be afraid to use it.

    Why not use a mig welder on it,unless it's in a place where you just can't do that.
    just an idea.

    Consumer goods : Bakeware
    RTV118 Translucent, one part, general purpose, self leveling pourable, acetoxy cure silicone sealant where flow into small crevices is desired. Used in thin-section potting, coating, sealing, bonding, insulating and encapsulating. Meets Mil specs, FDA compliance, NSF status, UL and USDA recognition.
    Hmmm. That might work.

    I don't have my own mig, and my friend who does has a tendency to tear stuff completely apart and rebuild it. I just need a hole filled. By the time I get it back from him it will have had the Tim Allen "Home Improvement" treatment.

    If it is a seam then a propane torch and lead free solder works wonders

    It's where the base meets the wall of the tank. I'm concerned that I can't get the galvanized metal cleaned and fluxed properly. I understand it needs to be cleaned with muratic acid and then tinned to get the solder to hold correctly.

    You are correct...... In that case a bead of caulk might be the best option.

    I am refurbishiing 2 Woodman 30 frame radials and I am applying spray on truck bed liner to the exterior. Will probably caulk the interior seams as you talk about and then paint.
