Technical FAQ
Can Brightside be used below the waterline?
No. It is designed for use above the true waterline only.
Is this a one-part paint?
Yes. It is a one-part polyurethane, so no curing agent is needed.
When should the finish be recoated?
Recoat when the existing finish becomes faded, chalked, scratched, worn or damaged.
Do I need to sand between coats?
Yes. Interlux specifies sanding between coats for adhesion and gloss.
Parts Desk Insights
Best use case: Adding a bold, high-gloss red to boot stripes, trim and accent areas, or refreshing topsides with a one-part system that is easy to apply.
Most common mistake: Applying heavy coats. Brightside self-levels best in thin coats, and skipping cleaning, sanding or surface preparation reduces adhesion and gloss.
Sizing and fitment guidance: This listing is 1 US quart. A quart is often enough for boot stripes and accents, while larger topside areas need more material once coat count is factored in. If you are matching an existing finish, confirm colour code 4248 before ordering.
