STARKE REPLENISH — SiO2 SILICA MAINTENANCE SPRAY

Think of Replenish as the insurance policy that keeps your sealant from failing.

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 and your sealant holds up the way it was designed to. It doesn't fade before its time. It doesn't fail. The protection you invested in stays in place.

Here's why it works. Replenish's carbon-infused SiO2 formula doesn't just sit on top of your existing coating — it chemically cross-links into it, adding a fresh reinforcing layer of protection directly into the sealant chemistry beneath it. Every application is strengthening what's already there, not just masking what's been lost. 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 its 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 sealant underneath performs the way it did on day one.

The result is a coating that reaches 12 to 18 months instead of burning out at 6. That's not a marginal improvement — 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 a fast no-contact application when time is the priority. Either way the cross-linking chemistry does its job and the coating underneath gets what it needs.

This is 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.

Monthly in active saltwater conditions. Quarterly in moderate or freshwater environments. Make it a habit and your coating investment pays for itself twice over.

Available in 16 oz. and 128 oz. Included in the Starke Clean System Maintenance Bucket.
