Someone near me is selling a Gecko 133 that I'd like to buy. However, in several places it's got fine cracks on it as shown here: https://ibb.co/6mB1svs. They say they bought the board new and have only used it a few times.
1) Are these cracks just superficial and cosmetic, or more serious?
2) If they're just at the very top level and cosmetic at the moment, could they develop into something more serious?
3) Is a DIY repair easy?
