Is this the appearance that you're seeing? If so, there's absolutely nothing that can be done. Many have paid very high dollars to have their coach sanded down and re-painted only to have the condition re-appear approximately 2-3 years later. I've done a bit of research on this and from what's been printed here on this and other forums, it's commonly referred to as "Crazing". Some will dispute the definition but, never the less, it's a form of fiberglass "checking" that was experienced by many manufacturers and models.
Supposedly it was caused by improper fiberglass sheeting being delivered to the manufacturer. If, you were real lucky and it started happening while your coach was under warranty, you got to go back to the factory and watch your coach completed "De-skinned" and have it replaced with the correct fiberglass. Then, it was all repainted to new and better specs.
But, approximately 90% of the coaches that exhibit such "crazing", are way out of warranty. And, if one chooses to have done what was done for the warranty customers, it's a seriously high cost repair. Just about no one does it. The cure, none, the answer, lots of wax, anc keep it in the shade as much as possible.

I was one of the lucky ones. My 2005 Phaeton was completely re-skinned in 2010 by Tiffin. My cost zero.

Indeed you were! Kudo's to Tiffin for stepping up and doing what was right. The estimate to do my coach is $30,000. Mine is not bad at all - I doubt anyone would notice it but I sure do because I detail my coach. the progression has been very slow over the past 8 years but it's there!!!!!
