CARPRO DarkSide — Tire and Rubber Polysiloxane Sealant

CARPRO DarkSide — Extreme Durability Polysiloxane Tire & Rubber Sealant

CARPRO DarkSide represents the pinnacle of tire and rubber dressing technology. Built upon a 60% high-solid polysiloxane matrix, DarkSide penetrates the porous vulcanized rubber structure to create an elastic, cross-linked protective barrier. Unlike conventional water-based or silicone dressings that wash away in the first rainstorm or sling greasy black marks down vehicle quarter panels, DarkSide chemically bonds to tire compounds, delivering a rich, deep-satin OEM+ look with intense hydrophobic self-cleaning properties that withstand harsh road grime, salt, and pressure washing for over 3 months.

Key Advantages & Chemistry

• Extreme Hydrophobicity: Repels rainwater, muddy slush, and brake dust instantly, keeping tires looking freshly detailed after torrential downpours.
• Anti-Browning Barrier: Seals volatile tire antiozonants within the rubber compound, permanently preventing ugly brown tire bloom.
• Zero-Sling Guarantee: Dry-to-the-touch formulation eliminates messy black splatter along lower doors, sills, and rear fenders when driving at speed.
• Long-Term Elasticity: Prevents premature rubber oxidation, dry rot, weather-checking, and hairline sidewall cracking.

Step-by-Step Professional Application Protocol

1. Deep-clean tires thoroughly using CARPRO ReTyre and a stiff scrubbing brush until rinse water runs completely clear of brown contamination.
2. Dry the tire completely using compressed air or an old microfiber towel. Rubber must be 100% bone dry for optimal polysiloxane bonding.
3. Dispense 2–3 pea-sized drops of DarkSide onto a dedicated applicator (such as CARPRO Tire Swipe or CARPRO DarkSide Brush).
4. Work the sealant evenly into the tire sidewall, working into textured lettering, lugs, and grooves.
5. Allow 15–20 minutes to absorb. If an ultra-matte OEM look is preferred, lightly wipe with a dry microfiber cloth. For greater gloss, apply a second thin coat after 2 hours.
6. Allow the coating to cure dry for at least 1–2 hours before exposing to rain or wet driving conditions.

Pro-Tips & Important Warnings

• Substrate Dryness is Crucial: Any residual moisture in the tire pores will compromise polysiloxane cross-linking and shorten durability.
• Do Not Apply to Treads: Strictly for tire sidewalls only. Never apply to tire contact treads, motorcycle tires, or bicycle tires.
• Applicator Maintenance: Clean your applicator brush with CARPRO Eraser or mineral spirits after use to prevent stiffened bristles.
