Great stuff.
Size: Powder Poli Ox - Pack of 6, Size: Powder Poli Ox - Pack of 6
My RV had moderate oxidation. I tried several polishes and waxes. Nothing worked well to make it shine out lasted long. I applied poly glow a week ago. It is easy to apply and made my RV shine like new. So far I love Poly glow and if it lasts anywhere a long as they say, I will continue to use it.

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.
