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?
Not all gel coats are equal. Most boats have a better gel coat than most MH front and rear caps. My BIL worked in a fiberglass shop and said there is a big difference and price in gel coats. Once the caps start oxidizing, they usually do no come back without a very large amount of work, and even than, they do not stay for much more than a year.
