poli glow shine
its works great .when applying more coats the shinier it gets
i used on several old boats because
the florida sun bakes the jell coat right off and no wax made can withstand salty seas , so why not ,, when you apply use the mit and don't gob it on .. nice and easy and recoat in five minutes when you get to about five coats you will be amazed.looks like new .. just a tip also after about a year or so and you want to re apply,, go to your local hardware store and get a gallon of high strength or non diluted floor stripper and put in spray bottle and use to remove old poli-glow also great for cleaning stubborn stains [ i use full strength ] just spray on and brush with a scrub brush and rinse ..and let dry and re apply ,, its also works on car faded bumpers ,, also never use harsh cleaners it will cause streaking the best thing i have found for cleaning the boat after poli glow was put on is car wash from auto store with wax or not it seems not to hurt the shine . it reminds me of mop an glow,,.

Poli Glow used on bottom portion of the picture
Just put it on 21 foot RV, was impressed with the shine. Key is to make sure the applicator is moist. I periodically dampen with water. Realizing it wasn't going to revive the stickers. Question is
How long it will last?
What will it look like after it rains?
Pictures attached, bottom portion was done with poli glow on June 7,2026 and I have just under a half of bottle left. Maybe I will update once it rains or how long the shine last.

40 Years Young and Ready to Bring My RV Back to Life!
As a happy 40-year-old guy who takes a lot of pride in his RV, I’ve been on a mission to remove all the oxidation and restore that clean, glossy finish. After doing my homework, I decided to try Poli Glow Boat & RV Restoration, and I couldn’t be more excited about the results so far. I honestly can’t wait to see what it looks like once I’m completely finished.
The quality of this product really stands out. It doesn’t feel like some quick temporary fix — it’s clearly made to properly restore fiberglass surfaces. The application use is straightforward, especially if you follow the prep steps carefully. Once I got into the rhythm of it, the process felt manageable and even kind of satisfying.
What impressed me most was the smoothness it brought back to the surface. Areas that were dull and chalky from oxidation are starting to look deep and refreshed again. It’s doing a solid job with light scratch removal too, especially the small surface marks that naturally build up over time.
I also appreciate the added layer of durability it promises. After putting in the work, I want something that’s going to last and protect the finish moving forward. And for anyone dealing with minor staining or corrosion spots, it definitely helps improve the overall look, contributing to better rust removal results around metal fixtures and trim.
If you’re like me and want your RV looking proud and road-ready again, this feels like a serious step in the right direction. I’m genuinely excited to see the full transformation once I finish the entire exterior. Definitely worth the effort.
