About eleven years ago when we lived in Wisconsin I tested some cleaner /polish/wax on the fiberglass surface of our motor home and promptly forgot about it.
Eventually I waxed the motor home several times and moved to Florida.
The Florida sun yellowed the fiberglass on the motor home with the exception of two spots where I tested the now unknown substance which remained snow white and incredibly protected right up until the day I sold it.
I now have a new travel trailer that I would like to protect but of course I can't remember what the magic elixir was that worked so well.
I hope someone has had a similar experience and can refresh my memory as to what I used eleven years ago.
Thanks
