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 would have an experienced RV detailer come out and take care of it.
Then it's easy for you to maintain from then on.
We did that with our RV 4 years ago, he was able to bring it back to life. It looked like it did when it was brand new.
I've used the spray car wash solution with wax each year since and it still looks new. http://www.turtlewax.com/shop/products/turtle-wax-quick-easy-zip-wax-car-wash-wax-64-oz
