Choosing points
- Best for bathrooms, tanks, exterior panels, and play equipment where lightweight molded resin is useful.
- Mold seams, gelcoat gloss, and rounded corners reveal molded production.
- Damaged FRP can show fibrous layers below the surface.
- Old gelcoat becomes chalky and dull outdoors.
How it ages
- UV, impact, water ingress, and surface coating failure can cause chalking, cracks, blisters, or exposed fibers.
What to avoid
- Do not leave FRP raw edges, back sides, or drilled holes unsealed in wet or UV-exposed use.
