IMHO, Poli Glow is the way to go. Our FB trailer was dull dull dull. I cleaned it then cleaned it again with the Poli Glow cleanser then applied the Poli Glow. The FB pops like it was brand new. I went to a rally
about a month after I applied it and fellow rally
goers could not believe how shiny it was. Follow the instructions. I applied the Poli Glow in sections about 4' by 5' (or so), waited one minute; applied the second coat; waited one minute... etc for 6 coats then moved on to the next section. Took not much more than an hour to do our Trillium
. Easy peasy; no polishing; just wipe it on in thin layers. When you put the first couple of coats on you won't think it is doing much but then with each successive coat it starts to shine. You can buy the Poli Glow kits on Amazon. In the states you will likely pay in the $75 range. For my Trillium
I used about a third of the polish bottle, so lots left for the coming few years. Look it up on Google to get more info.
