Part 1. Cleaning the underside of a mower deck in preparation of a new coating.

I wire brush mine. Sand paint off...if needed. Decrease and then soak it down with the acid. .rinse and paint...take spindles out and pack in fresh grease. .!!!!

Hey Mike, wait for part 2, spindles do come off. I never thought about acid washing it. That's a good idea. Thanks!

[@mikeschlup5279]

@29Turf ospho phosphoric acid or the POR rust solvent solution...I have even used an old chisel and scrape loose stuff off.. heck ,I have even sanded finished the POR and coat with rust bullet

[@29Turf]

@@mikeschlup5279 Hey Mike, I had never heard of rust bullet. But just checked out their website. Looks like some cools products. Thanks for the info.

[@mikeschlup5279]

@29Turf Decent product...POR is harder...smoother...they are both epoxy based...uses the moisture in the air to dry.

[@29Turf]

@@mikeschlup5279 have you found a product to apply over POR to keep the grass from sticking? Graphite, slip plate?

[@DANDY1]

Zinc! Coating of some sort?

[@29Turf]

Have you used it before? Does it work?

[@DANDY1]

@29Turf for a time it does, they use to heat metal up and apply wax as it cooled , lost art of iron smith's, baked the wax into the metal! I think thats how z Bart use coat inside cars as well! Prolongs it is all. Good luck!

[@29Turf]

That is interesting information. Thank you for sharing. I would love to know if anyone has tried it on a mower deck.
