Topsheet chipping and delam are two VERY different things...
That being said, post a picture, that way we can see how bad it is. If it's just normal topsheet chipping, they won't do anything for you, and the reason they won't is because it's simply a cosmetic issue, it does not and will not effect the ability or durability of the ski. However, a topsheet chip that penetrates the core is a problem, but one that can be easily fixed with some epoxy. However, a delam is when the top sheet separates from the core of the ski, this is a big problem, but luckily is usually covered by warrantee because it's usually due to a factory defect. So, again, post a picture then we'll be able to tell you what to do better. Also, if it is a delam, you'll need to take it to the shop you bought them from (unless you bought them from Nordica directly) because major ski companies (like Nordica) generally deal with warrantee issues with a shop as aposed to a customer directly (this is simply so they know the skis were purchased from a shop and aren't 2nd or 3rd hand, since after skis are sold to a second owner the warrantee is void, it's also so they only have to be in contact with a few people as aposed to the tons of customers).
