Worth the time and effort.
Perfect solution to my faded out, sun damaged gel coat. Follow the instructions to the letter for a factory-like shine. One bottle was barely enough for our 22' Winnebago, another bottle for our 29' Cabin Cruiser. Many compliments on the shine.

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.
