    Question. Typically how many hours does the paint last under the mower deck with a new mower? Our 52 inch Stander with mulch kit had no loss of paint until around 60 hours cutting cool season grasses with clay soils. Now at 80 hours seeing small sections that are shiny steel. I am guessing that 7 gauge steel will take a long time to rust through. Should we touch up paint or forget about it?

    i would touch it up. the cost is neglagent and it keeps the deck in good shape. it will rust and you will have more than a simple coat of paint to do.

    I found that if your somewhat gentle while cleaning the deck if you use a putty knife that it will last a longer amount of time.

    I'd say coat it with some rustoleum pro series paint or let it get some surface rust and hit it with por15. I've never had luck with por15 on clean metal, just slightly rusted, which they actually recommend you to let freshly sandblasted pieces get some surface rust on them before coating them.

    Well I have 220 hours on my machine and the paint on the underside has been gone for quite some time. You can really tell how the deck shoots the grass out the side by paint. I would leave it be.

    I can't imagine any rust building up on the underside of a deck. The grass blasting trough it should keep it pretty clean. That is why you don't have paint in those areas anyway. You'll just be repainting every couple hundred hours anyway.

    No point bothering. Mine get sandblasted back shiney on a regular basis.

    No point painting them for anything other than winter storage, and even then it makes more sense just to lube them.

    I decided this after I had the bright idea I would try that EZ Slide deck paint.
    I usually use the "Pro Grade" sprays from Krylon or Rustoluem with better results I think.
    (Unless I did something wrong with the EZ Slide)

    Anyways.... I'm thinking more along the lines of coating them with Fluid Film for the winter, or some Mil-Spec lube.

    Envy, do you have a link to the fluid film? Did you see my post here http://www.lawnsite.com/showthread.php?t=146499

    Try a can of Fluid Film right now on us. Check out our sponsored forum and ask for a free can today. Take advantage of it now before it goes away. I've been able to extend this offer past its original deadline, but that won't continue for long.
    The number of uses for Fluid Film is highly impressive due to its solvent-free application and natural lanolin base. Discover why Fluid Film is used by NASA for the Space Shuttle, why we have an exclusive contract with the US military for certain maintenance applications and why we remain the leader in rust/corrosion preventives and lubricants. If you don't believe me, check out our testing page to see how we stack up.

    Many areas of the 7 Iron II deck of my new John Deere 717A, 48" deck, were shiny metal after only about 10 hours of service. I was surprised because I seem to remember my Exmark Viking taking a long time to shine down to metal, in any area. The discharge force is vastly different between these two decks.

    The blades being used will undoubtedly make a difference. If I use regular hi-lifts on my Exmark, the underside may, or may not, stay quite clean of debris. However, when I use extra hi-lifts, the deck gets cleaned out, shiny and smooth pretty quickly. Therefore, most likely, the paint situation will depend upon what blades are being used and the kind of soil (sandy, clay, etc) is underneath the deck.

    If grass clippings won't clean it off smooth, leaves during Fall cleanup will certainly do a job!
