I am looking for the SIC codes of manufactures that build products out
of fiberglass.

Examples of industries include, but are not limited to, manufacturers of:
Boats
RVs
Surfboards
Prototypes
Custom automobiles
Furniture, i.e. jbiindustries.com
Tubs and Jacuzzis
Companies that build sets and props for theatre, film and amusement
parks, i.e. storlyandstudios.com, dreamation.com
Etc.

I would like to have this project completed by Monday November 1st.

Dawnw,

3089 = 326121, 326122, 326191, 337125
3229 = 327212
