Is your MPG roof oxidized?

We have a 2011 MPG, and last fall I noticed that our roof was noticeably oxidized. I was surprised since the roof and front & back are one piece fiberglass. The front, back, and sides are still glossy and smooth, and polish up fine.

I would have expected it after 5-10 years, but not this soon.

Is this normal for a fiberglass roof? Anyone else have this issue?

Thank you

marc, I also have a 2011 MPG with severe oxidation on the horizontal surfaces. At first I thought it was an anti-skid coating....nope! Should this happen on a two year old trailer? Have you come up with a fix? I really like my MPG and would like her to stick around for a while.......
