Has anyone painted metal surfaces with Glyptal , POR-15 or other HD paint . Something resistant to wear to apply to the underside of a lawnmower deck to reduce the amount of glass clipping stuck to the deck?s surface .

I sandblasted the 46" deck on my 332 JD and then followed the POR 15 instructions exactly. Looked good for a couple years and then started to wear through. The soil here is sandy, and when it is dry, with thin grass in spots, the underside of the deck is basically getting sandblasted all over again. I would not do it again in my case. Now if you are usually cutting lush grass I think it would be worthwhile. My $.02.

Linex can do a bedliner coating version that is rock hard and shine slick.

Glyptol would not work. It's very soft and would not hold up to the elements or abrasion.

Por 15 would work ,but it's surface when dry is not as shiny or slippery as an enamel. I would clean and paint it every year with a good enamel and you may get a cleaner discharge of cut grass.

I paint top drive gear boxes on every rebuild with glyptal. I sure don't think its soft. and im sure it would prevent grass sticking. plus the red stuff is better than the grey stuff.

I've used a product that has worked pretty well under my deck, called "Modeck". I got it at Walmart...

Back in the 70s I worked at a machine shop that part of our work was machining cast iron gear boxes. The interiors were painted with red Glyptol. It seemed pretty tough and sure made getting all the cast iron chips and dust cleaned out easy. I was told the main reason though was to seal any porosity in the casting that might have caused the box to weep oil. Not sure how it would do as far as helping keep grass from sticking to a mower deck, but it sure could not hurt.

I've painted some stuff with silver, and some with black. The silver came out quite dull, but the black was very shiny. Not sure if the difference was in surface prep or something else. This was on a deck that I put away because of value, so I can't comment on how long it lasts.

If powder coating you would want to use green so that the pieces blend into the grass as they fly out.

Man has not yet invented such a paint that cannot be chipped by sticks and stones flying at supersonic speeds, or that grass won't stick to.

You need something hard and smooth so the grass will flow out the side or back

Toughest paint I can think of is 2 part epoxy paint .

Let me know how it works out

I know someone who tried that, but it did not work well. Then he put a 4 blade disc in place of each blade, that worked real well. I did a little work on the mower, so I did see it first hand. He bought the disc set up at the Louisville farm machinery show, I believe. Mark.

I am expecting the paint to require a touch up at least once per season .

Double 07 down below has the best idea. Use a black pick-up bed liner. Don't spray it but brush it on and heavy so it will flow level and not be rough. I've used it and it's the best. You won't have to re-do it . Slick , hard surface and flexible.

Randy, I agree that bed liner would be the best top coat, however, in that environment it will separate and come off in chunks if the rust is not first "killed" and at least a primer put over it. Bed liner instructions will tell you that.

The plan was to high pressure wash the underside of the deck to remove all loose material. Then dope the metal surfaces with phosphatic acid metal surface prep prior to a primer coat .

Exactly the right way. just pressure wash after the phosphoric acid product to remove any residue before priming.
