Hi, I change my old b3 for new b5 (8, 11m2) Black color

. Nice kites, nice graphic but.....
after 6-7 times of use on both the golden color is going down. So the kites looks like they are few seasons used

. I kite only on my local spot with grass on beach, so no sand or sun couldnt damage them.
Does any one of you have the same problems?
