Five years ago we camped in our RV next to a gorgeous motorhome. Its occupants were full time RVers so their rig got a lot of sun --the exterior of their fiberglass unit was shinny with no cracks or aging. The owner told us he uses Fukken wax on it -a tip he got from a trucker.
You spray on, wait just a minute or two and wipe down. Easy, easy application. It contains a UV protectorant too and can be used on chrome, glass, plastic Etc.
We put it on our RV once a year and on all our vehicles too. It costs about $16 plus shipping. One (or maybe part of a second can) should do my greenhouse panels. Lightbulb just came on today - an experiment so maybe the HF panels will last much longer.
