Does coating the underside of deck really work?

[Diamond Jim]

I purchased the body undercoating and it is as thick as you can imagine. I have used it on many other jobs.

What I have found the spray on non stick products do , is make the deck easier to clean . I mow about a dozen lawns per week . I Clean , and Sharpen once a week (scrape and pressure wash) on the weekend . After letting the deck dry completely , I spray it liberally with no stick , put the Blades back on , and repeat . Keep paint on the deck at all times . Needless to say , the lesser lift a blade has , the less it fowls the deck , and throws stones . I run a Gator G-6 Blade , most of the time . I'd like to CeraKote a deck , but haven't figured out how to bake one yet !

In the spring when I'm getting the mowers ready, when the front is in the air so I can
access under the deck. I'll scrap/power wash as best I can and take some old cans
of spray paint, maybe several different ones. And spray the underside...really cover it
well. Prolly lasts through 3 - 4 mowings.

Do what you're doing in the fall , instead of letting the grass rot out your deck ! Decks cleaned before storage will last longer , as will decks cleaned more frequently ! I service mine every week .

POR 15 chassis coat will stand up to the abrasion
Man bullets bounce off that stuff when fully cured
However it HAS to be done properly which takes a very long time to do

Just buy a mower with a good heavy fabricated deck ,remove build up grass after each mowing and it will last longer than the rest of the mower.

Has anyone tried something like that spray-on bed liner, without the grit?

I have used the bed liner for the last two years with good results. Three years ago I sand blasted the rust from the 10 year old deck and primed and painted. Realizing that would not work, the following year I pressure washed and used Rustoleum bed liner spray. Results were impressive, so the following year I again used the pressure washer and bed liner. This is done after removing the deck, a 5 minute operation. Considering the cost of a replacement deck plus truck freight, this is the way to go.

Will the bed liner spray hold up when you do a occasional deck scraping if it gets loaded with wet grass. Will scraping remove the coating easily?

Short answer in my experience ----------- NO. ( 1 ZT , 4 tractors & about 6 push mowers )

I haven't tried scraping the underside during the mowing season, rather using a water stream instead. The bedliner is mostly intact when the deck is again removed for service. Here the mowing season is 12 months, so I think the bedliner is a good, easily applied coating giving 12 months of protection.
