Mower Deck Protection
 

Has anyone tried using spray on truck bed liner on the underside of a cleaned and painted mower deck?

My dad used some form of aircraft tank enamel. It still came off. I would think the texture of bed liner would attract grass sticking even worse.

Slick and shiny works best.
Truck bed liner would not be an option for me.
Would you spray it on your snow thrower chute as well?

Perhaps Fluid Film?

I have used liquid bed liner, specifically Duplicolor brand.
It comes in a very thick consistency, sort of like wood glue.
You can brush, roll, or thin it and spray on.
Brushing and spraying gives you a textured finish but brushing lets it run out smooth,
so brushing is the way to go.
It's thickness also allows it to settle into pits in the metal giving you even more smoothness.
Before applying, thoroughly clean the surface and prime with Rustoleum Rust Reformer.
All that being said, NOTHING you can apply will last indefinitely, so if you are looking for a one-time fix,
keep looking.

Keep it clean, don't mow when it's wet and don't leave it sit in the yard/grass when not in use, pretty simple.
Condensation Ya know, does a world of harm to anything metal.

I find the same results as Iron Man, nothing lasts.
Much like living on a dirt road, ones vehicle does not stay clean very long.
If a person infrequently mows or it is a small lot, a covering of paint will last
much longer.
But grass is not the only "stuff" that passes out of the deck.
Things like abrasive dirt, sticks, mulching leaves. etc etc. just wear the covering off the deck.
I find after the last yearly fall mulching of grass, the underside of my old 50" deck is as shiny as if it was just sand blasted with fine abrasive.
Several times I painted it to no avail, as the next year it is bare again.
Now not to say all of it is bare, naturally it was just where the debris can attack the coating.
I will freely admit most of my "grass" does not look like a manicured golf course, quite the opposite.
Just my take.

I use Fluid Film on our snow thrower with good results. I re-treat 2 or 3 times in a season. No experience with mowers.

I had not heard of Fluid Film until this thread,
interesting reading here,

I'll give it a try, thanks for the input.

I cannot remember the exact information, but I have read on another forum about people having good luck with oiling the underside of their decks a specific way. IIRR they removed the deck and recoated it every year or so. Prevented rust and kept grass from sticking to the deck, but not a permanent fix.

I personally doubt there is ever going to be a permanent fix, but you never know :bigthink:
