Bob,
I work as a production supervisor in a fibreglass factroy ,we are making parts for Lotus both current models and replacement parts for old models ,We also make race car bodies ,i'm also quoting to do the fibreglass items on a small 'kit' biplane .We have a small pattern/design shop and i spent 8 years working in that dept.
As with fibreglass I do end up doing repairs on the side for reliants,bugs,scootercars etc.I'm also making a few race car parts for old classic racers.
