Hi Darryn
Thats not bad, mine are 1992 as well. I've only just(probably two weeks ago) filled a couple deep scratches in mine, as well a small delamination of the trailing edge on one, which wasn't easy to fix because of a couple of grains of sand stuck between the two halves, but I'm happy with my repair, and will get resprayed before next season.
Regards
Matt
