Wish I Had Used This Sooner – Stop Debating and Just Buy It! After a lot of debate, extensive research, and way too many hours spent using other products trying to restore and protect my RV's fiberglass that never fully delivered the results I was after, I finally tried the Poli Glow Deluxe Kit—and I am extremely happy I did. My only regret is not using it sooner instead of letting other people's opinions talk me out of it. The 6-in-1 complete kit is the right way to tackle fiberglass restoration from start to finish—eliminating oxidation, restoring the shine, and then protecting it long term all in one comprehensive system. The difference in how my RV looks after going through the full Poli Glow process is genuinely impressive and far beyond what any single product or traditional buffing method I tried before could deliver. The oxidation came off cleanly, the restored shine is deep and glossy, and the long-lasting protection gives real peace of mind knowing the fiberglass is shielded from UV damage and the elements going forward—especially important in the brutal Las Vegas sun. For anyone who has been going back and forth on whether to invest in the full Poli Glow Deluxe Kit—stop debating, stop listening to everyone else's opinion, and just do it. The complete system delivers complete results, and I won't be using anything else on my RV going forward. Highest possible recommendation.

Great stuff.

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!
