A quality product which will clean an oxidized fiberglass trailer in preparation for the application of Poli Glow
I used this to remove the Poli Glow previously applied about two years ago to my fiberglass trailer. It seems to do a slightly better job of removing the PG than the other Prep solution, but I didn't do a side-to-side comparison. And the surface never achieved a completely uniform appearance after the stripping, although this may not be possible because of differences in the remaining gel coat surfaces. I also completely washed the trailer with soap & water after using this stripping product. I didn't do this the previous time and thought some of the prep compound may have been left on the surface resulting in a shorter life. Time will tell. Note: it is still "work" to strip the trailer, this is not a "magic" solution, thus the 4-star rating. But it, along with the Poli Glow, was the only way to get my oxidized trailer to look shiny. All the other products tried failed to bring a glow. I will purchase it again when redoing the trailer.

Does not work.
Do not use this product. It has left my RV all splotchy. It looks terrible. I am trying to find something that will work. I wish I had never used Poly glow to start with.

Must have for campers
This stuff is amazing! Made our camper look brand new with the polish they sell in this brand. Would use nothing else on it.
