I have a 14 year old fiberglass shell motorhome and I can't get the shine to come up. I've tried the top brand car waxes to no avail. Can anyone recommend anything?
I used the ZEP on a 24 yr old Motor home. Preped with Mr. clean magic erasers. It looked brand new. Kept the shine for three years till I sold the unit. I would do it again in a second. In fact I plan to do it to my new to me 2004.
