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.
