Hi all, First time posting but have been reading, learning for some time. I have a 997 Zero turn and mow about 7 acres every week. Had to mow some wet spots earlier and was shocked at the build up. Must have taken 30 lbs scraping the deck. I searched for the answer to this dilema and the most common reply is Fluid Film. It may prove to be the best but it's not immediately dry so that makes me wonder. I'm an engineer and wanted to prove what is the best. This is not a scientific test, and your results may vary. First thing I did take the deck off and wash the bottom, spent a bunch of time prepping the metal and just got done with my first coat of POR15. I wanted to start with a smooth hard surface and this stuff is tuff as nails. Will put second coat on in a few hours. I also metal prepped and POR15'd the blades, here why: I want to do the testing on the blades first. I'm afraid that if I coat the deck with something that doesn't work, then it may stop the adhesion of what I find is the best. So I will first see what works best to keep the green crud from sticking to the blades. This way I can also make sure it wont eat through the POR15. If anything works on the blades, I would think it should work better on the deck. I double bladed my deck this spring, two blades on each spindle, crisscrossed and tack weld to keep them at right angles. This gives me plenty of surfaces to work with. The green crud was almost quarter inch thick on the blades near the spindles and it was even on all the blades. I've notched the blades so I can keep track of what product I used where. So what coatings am I going to try? I did as many hours of research and ended up deciding on the following: Fluid Film Liquid Wrench Silicone spray Dupont Teflon Silicone Lubricant Dupont Teflon Molti-use dry wax lubricant Dri slide dry film lubricant with moly and graphite Sprayon Premium mold release PTFE Carnuba car wax Meguiars Gold Class Car wax and finally - nothing - just the POR15 paint Yes, I know there is other stuff I could try. Pam would seam to be a very short term solution and I'm looking for something that will last. I went by what will repel moisture and remain slick. This is all stuff I could get my hand on in two days. I will coat 1/2 of each blade top and bottom with 2 coats of each product. I listed 9 tests above, that leaves me three open blade halves because I'm double bladed. Any suggestions? Need them fast. I have an above ground hoist in my shop so I can easily check the results on a weekly basis. Once I've figured out what works best, I will take the deck off scrub it clean and coat the whole thing. If nothing works, I will be dissappointed to say the least If I find the answer it will be easier for all of us What do ya think?
