It Works!!!!!
Size: Powder Poli Ox - Pack of 6
We have only completed the first two steps it Poly Glo set we purchased and has it ever made a difference in the look of our hauler/trailer! The dull oxidize black color is somewhat shiny. Cant wait to put the final two steps on it! A little elbow grease and work did wonders! We will share a photo once the procedure is complete!

Could be good
Size: Powder Poli Ox - Pack of 6
I cleaned my RV very thorough from top to bottom before even starting the process with the Poli Glow system. Here's what I learned despite videos and lots of reading reviews.
1. Must be very clean and clear of anything you dont want to stick and show on your final outcome.
2. It takes more coats than you think it would (after 3 coats) it was still really streaky and I was starting to regret using Poli Glow. I ended around 7-8 coats and my rig had no major oxidation at all.
3. As one reviewer said, use a clean microfiber cloth v the applicator that comes with it, I found much better results with no lines.
4. Dont go to heavy on the coating, the instructions say this, but I went super light and it can be very easy to get lines with heavier application.
5. Dont look at your work after 3 coats, you will feel deflated, just keep going for at least 6 coats and then look at your work.
6. Only do small areas and look out for drips and lines, you need to get them out right away.
7. I did not use the Poli Ox, I was able to get any oxidation out with just the Poli Prep
8. Going up and down a ladder for hours sucks!
9. I hope it will come off in the next couple of years when I plan to replace the decals. Honestly, thats my biggest fear is how hard it will be to remove when the time comes.
10. After a scary start, I will say it did turn out pretty nice, was it easy, nope, would I do it again? Not sure, I need some time for my back to heal up!
If you do choose Poli Glow know there are other options that maybe a better way to go such as wet sanding etc. Poli Glow is pretty good, but it can be pretty bad also if the surface is not cleaned and the Poli Glow applied correctly.

Good but DO NOT USE APPLICATOR MITT
Size: Powder Poli Ox - Pack of 6, Size: Powder Poli Ox - Pack of 6
The poli-ox worked well, just know that it will require several applications to remove old buildup and oxidation. once you are done, the paint will still look oxidized, but once you put the sealer on, the color will be deep and shiny.
The sealer itself is supposed to be enough for a much bigger RV than we used it for. (17') We used 3/4 of a bottle for 1 side, due to the fact that we would remove and start over because it left ridges like a brush in paint. On the second side of the RV, we scrapped using the Mitt, and low and behold, using a microfiber towel to apply solved all of the issues. No more ridges and the remaining 1/4 of the bottle was enough to apply 5 coats. The mitt also wastes a LOT of product. So be warned use a Microfiber towel (that has been previously washed) and it will save you a LOT of time, money and angst.
