I have tried several metal "polishers" and for the most part been disappointed. The latest was the 303 metal polish.
One thing to note, is that FIRST using the green colored de-oxidizer makes a HUGE difference in the outcome, just using the purple metal polish does not deliver nearly the same result and had I not bought the combo pack, I likely would have been disappointed again. I rarely write reviews but was impressed enough to make the time to write this one partly due to results and the fact that its been so hard to find a meta polish that works, but ALSO so people know that its important to have BOTH BOTTLES and follow the directions to get the results you will want since it makes all the difference using the de-oxidizer first.
I purchased this mostly cause I have a 2014 Centurion wake boat which has stainless on it and the trailer has diamond plate step pads on fenders and few other spots, sadly I had not found anything previous to this that worked well so the trailer diamond plate had not been maintained and was fairly dull looking. I saw someone on a boat forum recommend this cause he used it on his diamond plate when is what got me looking at this product since I had pretty much given up due to 3 other products I have tried being a giant waste of money IMO, so I was hoping this was not gonna be another $30 flushed down toilet.
I am pretty impressed with the results, the diamond plate now looks virtually brand new and literally sparkles. Also did a section of a 3yr old truck toolbox that has never even really been washed and sits on my work truck outside 100% of the time, this polish also transformed the toolbox and brought back all the shine. Only thing I will *NOTE*, on the diamond plate where the polished sections are, the purple polish has small "beads" in it which I am sure is partly what helps polish the metal an bring it back to original shine....but it did leave some very small "swirls/scratches" in the polished diamond plate when done. Maybe that is a softer metal? This happened on trailer step pads and the toolbox, its only something you can notice and see when looking at it from real close up, but since I am OCD, I notice everything! Also important to note that on all the metals I have now tried this on, the polished areas of the diamond plate is the ONLY one that this happened on. None of the other polished metal I have used it on got any swirls at all and why I am thinking perhaps the diamond plate is a softer metal or perhaps something else.
On my boat, I have several stainless steel, polished wakeboard racks on the tower that were covered in water spots that I have been unable to remove no matter what I used in the past. Not gonna lie....it was time consuming cause I disassembled the racks totally to thoroughly clean every piece perfecty, but the difference is incredible, 5yr old racks now look brand new! I found on the areas of metal that are "brushed", I would use the de-oxidizer, let it sit and dry.....then use the purple polish (some required multiple coats to get all the water spots/crap off (doing smaller sections at a time is key) but I also think it was more work mostly cause its the first time they have gotten cleaned like this in 5yrs), THEN, because of the black residue that comes off as you polish the metal, in the sections where the metal has the "brushed" metal (like really fine groovse in metal), a very fine coat of the black would remain in the brushed metal grooves (maybe cause I never used a "damp/wet" cloth, only dry microfiber cloths?). Anyway, 5mins later I would go back and use the de-oxidizer again and it easily removed ALL the traces of the fine black residue from the purple polish and left the brushed metal looking perfectly shiny and brand new looking.
FYI.....Because of the black residue coming off, which means its doing its job and removing the buildup, you will need multiple cloths.
One other thing, I have custom rims on the trailer (brand is: gear alloy), and the very outer part of the rim has a brushed metal.....this has also gotten some water spots/residue over the years. You can only see it when very close up, but being OCD this has always bothered me. I have not done the entire part of a rim yet, but the other night did 2 small sections as a test. You can clearly see that this is removing all the water spots/residue and is also going to make those 4 rims look brand new, stoked about that!
After done with the metal polish, I tried "sealing" with Jescar (Menzerna), Power Lock +, which is a polymer sealant to see if that will help protect it. I have previously used this on a variety of surfaces and it works great and leaves no residue like some other waxes/sealers I have tried.....it worked well on the polished areas. After a couple tests, I found that my regular Paste Wax (Collinite 945), works very well on the brushed metal. Basically I put on a light coat and then without leaving it on for a while, I wiped it off. It left all the metal parts with a nice, slick finish that I am sure will help protect it a little bit better than with nothing.

Works great!
This is 2 products, the Deoxidizer and the polish. If you follow the instructions it works out pretty good! You can see the before picture here, this is after a regular car wash. Then the after is after both steps of the product.I used a rag for the Deoxidizer and a piece of carpet cut down to a 3x3 inch square to apply the polish. This diamond plate is 7 years old on the front of a trailer so it had rock chips ect.Overall I'd buy it again. It is a bit of an arm workout if you have a lot of square footage to handle.

Amazing stuff! Kudos to the manufacturer! I purchased this 6 year old motorcycle trailer from a gent who had it placed in long-term storage. Significant oxidation was a problem and the aluminum diamond plate was very dull. Took a chance on this product and glad I did. After application, the diamond plate bed looks almost new again. The process does take a bit of elbow grease but not bad at all. More time consuming than hard work. I had about 5 hours invested in this restoration, taking my sweet time. The product goes a long way...still have 30% of the deoxidizer left and 50% of the polish after completing the project. Both 12 oz bottles. Crazy cool product! Worth its weight in gold! Get some, brothers and sisters!
