BTW the sock fix is fine IMO. A helmet made from a bag of styro peanuts would provide the same protection, as long as something held them in place and you had the same depth of material overall.
UV degradation is real, but its extent is *far* less than people imagine. Prolonged exposure - that would be leaving the helmet out in the sun every day, with the plastic cover missing - will result in yellowing and a covering of dust from the degraded Styrofoam. The thickness of that layer of dust compared to the thickness of the helmet represents the (trivial) reduction of impact protection. My opinion: there is nothing wrong with repairing a damaged bike helmet.
