Quantum 4599 Primer Sealer Base is the base component of a two-part, fast-drying primer sealer system that can be used as a spot primer on a finished, primed surface to seal underlying products where breakthrough has occurred, or as a finish primer on prepared fiberglass and gelcoat surfaces where fairing and surfacing are not required. Overcoat with Quantum 99 Polyurethane Topcoat for a smooth, glossy finish and improved topcoat durability.
Quantum 4599 is easy to mix at a 4:1 ratio with Quantum 99 Spray Activator (required, sold separately), and easy to apply by HVLP or conventional spray gun, with excellent flow and leveling properties. This fast drying primer system can be overcoated with Quantum Quantum 99 Polyurethane Topcoat after 1 hour - without sanding.
Available in White, in Quart and Gallon sizes. Note: Requires Quantum 99 Spray Activator.
