Back with a report on my Rv project. My 2004 Newmar fifth wheel, although I washed and waxed it regularly, was beginning to show it's 8 years. With everyones suggestions here, I worked on it for a good week. The trailer was not beyond repair. I used the fiberglass restoration kit and could not be happier. The front and rear caps look like new. The sides are very good but some slight blotching can be seen at some angles. All in all, I'm well satisfied with the results.
That said, I also bought the DA orbital buffer and did not have the best of results with it. The buffer performed well but not very long into it's use, I started having problems with the pads staying on the buffer. One pad came apart. I contacted Maguires and they did send me some new pads and a replacement wheel but not much changed. The company I bought the buffer from sold me a wheel made by a competitor and it has two or three times the ability to hold the pads. I did not have any further problems. The pads they sent worked flawlessly.
I have always believed the Maguires products are the best available and I still have great faith in the waxes and cleaners. I'm sorely disappointed in the buffer and pads. They need some real work.
Thanks again to everyone for their input. This is a great source of information.
