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.)

Worth the time and effort.
After proper surface prep and 6 applications, my badly sun damaged RV shined like new, with many compliments. However, after a few months under the cover, the fiberglass surfaces that were in contact with the occasionally wet cover in the Florida sun discolored badly, and will have to be wet sanded and the coating re-applied. Also, the polish does not hold up well where boat fenders rub against the coating, and it wears away in cockpit areas that are heavy hand traffic, like hatchways and around handrails. Overall a decent product, I will probably re-apply in a couple seasons.

Brings old paint back to life.
Best product for fiberglass oxidation. Tried many different wax’s and compounds. Poly Glow did what the wax could not do.
