It doesn't age faster. It ages differently. Because it's not a plastic, it doesn't get smeared & pushed around like a poly finish does. This allows it to rub off, flake & chip differently. As for the gloss, that's just what they buff it to, instead of satin. The finish is still the same.Nitro ages faster right? But this is nitro gloss. Does it still age and legitimacy relic over time?
