Wish I Had Used This Sooner – Stop Debating and Just Buy It!
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 buffing my RV with other products that never fully delivered the results I was after, I finally tried Poli Glow—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 difference in how my RV looks after applying Poli Glow is genuinely impressive. The high-gloss finish it lays down on the fiberglass is deep, clean, and long-lasting in a way that the other products I tried simply could not match. The application process with the included mitt is straightforward and far less labor-intensive than traditional buffing and polishing methods, which alone makes it worth switching to. The hydrophobic properties mean water beads and rolls off beautifully, and knowing the UV protection is working to shield the fiberglass from the relentless Las Vegas sun gives real peace of mind for long-term appearance and protection.
For anyone who has been going back and forth on whether to try Poli Glow or sticking with whatever you've been using—stop debating, stop listening to everyone else's opinion, and just try it. The results speak for themselves and I won't be using anything else on my RV going forward. Highest possible recommendation.

Works Great, A Lot of Elbow Greese, but Worth the Effort!
Transformed our motorhome exterior . It looks new, brighter, and no haze! It helped to watch the instruction videos on YouTube.

Wow just wow. It works great.
I have a 2017 vengeance and it has had a bit of sun even though it stays in a building when not used. It was getting a bit of fading even though I polish it each year. I wanted to try something and this was what I settled one after looking. Yes it is a bit of work on a 43’ fifth wheel. I ordered 2 kits but after a week of working on it after work we went camping and where next to a week old fifth wheel and he asked what I used to make it look better than his. It has a mirror finish on it now. After 6 months it still looks great and it’s durable and ease of use. What an effective product

Great product for rv
This is an excellent product. The front of our camper was very faded from the sun even though we keep it under a cover. After four coats, it looks like a different RV. We are going to do the entire camper. The difference is amazing. You will be so happy with the results. We would give it a 10 if possible.

Amazing fiberglass restoration.
So easy to use and fabulous results. A few years back I had tried Maguires products to restore the shine on a 5th wheel. That was so labor intensive and the results were struggled to achieve faded quickly. I hesitated to Poli Glow due to the cost and our prior attempts lackluster results. I was able to get the restoration kit at a discount on Black Friday through the stores website and tackled the camper with the temps between 60-90 as instructed. I bought 2 of those kits just to find out that due to the climate and UV exposure the number of coats I would need for the Poli Glow was going to exceed the amount I had on hand through the 2 restoration kits. So I had to scramble to buy another bottle of Poli Glow. Applying this product is just time consuming and not difficult. Make sure to properly prepare the surface before using poliglow. The whole system turn a badly oxidized camper into a shiny finish. I am truly shocked. Hopeful the results will last a while.
5th wheel camper 40 foot long.
I have used 3 poliglow bottles (12 coats), 1 bottle poli ox, 1.5 bottles of Poli wash (of course, not in that order). I potentially need 1 more bottle of Poli Glow to finish nose cone/basement area (basement area is still in good condition so may not do this area if I can get the nose cone with the remainder of the Poli glow I have.)
