- **[Core]** Mix catalysts into resins, and saturate cloth and mats with mixtures, using brushes.
|
|
- **[Core]** Bond wood reinforcing strips to decks and cabin structures of watercraft, using resin-saturated fiberglass.
|
|
- **[Core]** Check completed products for conformance to specifications and for defects by measuring with rulers or micrometers, by checking them visually, or by tapping them to detect bubbles or dead spots.
|
|
- **[Core]** Trim excess materials from molds, using hand shears or trimming knives.
|
|
- **[Supplemental]** Repair or modify damaged or defective glass-fiber parts, checking thicknesses, densities, and contours to ensure a close fit after repair.
