Starke Replenish SiO2 Silica Maintenance Spray | Marine & Auto Detailing
STARKE REPLENISH — SiO2 SILICA MAINTENANCE SPRAY
Built for the Pacific Northwest. Engineered for saltwater, rain, and everything the Salish Sea throws at your hull or paint.
In the PNW, coatings don't fail from neglect — they fail from accumulation. Salt spray off Puget Sound, mineral-heavy rainfall, organic fallout from coastal tree cover, and constant UV cycling through marine overcast all suppress hydrophobic performance faster than in any other environment in the country. Replenish is the answer to that specific problem.
Every SiO2-based coating and sealant in the Starke lineup — Repel Pro, Liquid Thor, Hyper Hold Pro, Hydro Guard, Revolution — has a maintenance partner. That partner is Replenish. Apply it monthly in active saltwater or heavy-rain conditions and your sealant holds up the way it was designed to. It doesn't fade before its time. The protection you invested in stays in place.
Why it works differently than a detailer spray. Replenish's carbon-infused SiO2 formula doesn't sit on top of your existing coating — it chemically cross-links into it, adding a fresh reinforcing layer directly into the sealant chemistry beneath. Every application strengthens what's already there. That's the difference between a maintenance spray and a coating reinforcement system.
Environmental contamination — salt residue, mineral deposits, organic fallout — builds up on every sealant surface over time and gradually suppresses hydrophobic performance. The coating is still there. It's being buried. Replenish clears that suppression and bonds fresh SiO2 chemistry back into the coating in the same step. Slickness restored. Gloss restored. Anti-static protective layer reestablished.
The result: a coating that reaches 12–18 months instead of burning out at 6. In PNW saltwater conditions, that's not marginal — that's the difference between a maintenance schedule and a replacement schedule.
Two application methods. Spray on and wipe off with a clean microfiber for a deep glossy show-finish result. Or spray on and hose off for fast no-contact application when time is the priority. Either way the cross-linking chemistry does its job.
Not a detailer spray that streaks on application and hazes in the sun. Replenish is a professional-grade formula — user friendly, intensely slick, deep gloss, clean finish every time. Compatible with every SiO2 coating and sealant in the Starke lineup.
Recommended cadence: Monthly in active Puget Sound or coastal saltwater conditions. Quarterly in moderate freshwater or inland environments. Make it a habit and your coating investment pays for itself twice over.
Available in 16 oz. and 128 oz.
Frequently Asked Questions
What surfaces is Starke Replenish compatible with?
Replenish is compatible with all SiO2-based coatings and sealants in the Starke lineup, including Repel Pro, Liquid Thor, Hyper Hold Pro, Hydro Guard, and Revolution. It works on marine gelcoat, painted boat hulls, automotive clear coat, and glass.
How often should I apply Replenish in Pacific Northwest conditions?
Monthly in active saltwater or heavy-rain environments like Puget Sound, the San Juan Islands, or coastal Washington and Oregon. Quarterly in moderate freshwater or inland conditions.
Can I use Replenish as a rinse-off spray?
Yes. Spray on and hose off for fast no-contact maintenance, or spray on and wipe off with a clean microfiber for a deeper show-finish result.
Does Replenish work on top of ceramic coatings?
Yes. Replenish cross-links chemically into existing SiO2 coatings rather than sitting on top of them, reinforcing the coating chemistry beneath rather than just masking surface degradation.
