Is gel coat crazing purely a cosmetic problem or does it pose a threat to the structural integrity of the underlying fiberglass?.

About 28 years ago I refinished a glider (an ASW-17) with Simtec Prestec - which was then a somewhat new product for glider refinishing ( it was originally sold as a coating for radomes). The glider is now in Canada. Can anybody tell me today how that product has held up over time (compared to the original Vorgetlat and Schwabelack)?
