Looking for suggestions for the underside of my ZTR mower deck. I pressure-washed it today and most of the original factory paint is long lost.

Could you use some of the truck bed liner paint? Obviously not the products with the rough texture. Or simply cleaning, then paint a thin coating of oil prior to storing the mower? Or maybe a hardened epoxy paint coating?

I use rust converter. It turns black and bonds quite well.

"Hardened epoxy paint" would be best, but I might also consider Fluid Film.

I use Fluid Film for its rust prevention, not to keep the deck free from buildup. There is absolutely nothing left of it after each mowing. I use a Country Clipper zero turn with a standup deck and clean it completely after each 2.5 acre mowing, the last time there was at least 3 gallons of buildup despite the coating. No, the grass was dry and the mowing was done in the afternoon so there was no dew.

Would you use the Fluid Film over raw steel? A lot of the original paint is worn away on the underside of the mower deck.

You might be able to find some orange paint on the underside of my mower deck, but not much. I pressure wash the underside after the season and let it dry. I empty a full can of Fluid Film on it. During the season, I blow out the underside after each 2.5 hour mowing. It is a little easier with the feature that allows me to flip the deck up for better access. I used the same procedure on prior mowers and it seems to work pretty well.

Anyone try silicone spray? When I had my cub cadet with bagger, used to spray the tube to help prevent clogging.

One can of Fluid Film in one application? You ought to buy in by the gallon then, much cheaper!!
I have thought about buying it that way. But, since I only apply it after the season, it's not too big of a deal.

if you want to paint the underside
remove deck, remove everything to the bare shell, sandblast, use 'aircraft' grade epoxy,FOLLOW the directions to a 'T'. It'll last 12-14 years minimum.
