Choose Your Formula: The Grog Refill System
Grog Refills are a complete system of premium inks and paints, each engineered for a specific purpose. The key technical distinction is between paint and ink. The Grog paint range consists of pigmented formulas designed to create a solid layer on the surface, offering high opacity and a glossy finish. The Grog ink range is composed of dye-based formulas engineered to penetrate and stain the surface, ensuring maximum permanence. This system of specialized Marker Refills is designed for use with Grog markers such as Squeezer™ and Cutter™, as well as with Empty Markers, allowing for full tool customization.
Mercury Chrome Paint™ (MCP): The True Mirror Effect
The Mercury Chrome Paint is a specialized alcohol based paint formulated to produce a flawless mirror finish. Its unique chemical composition relies on ultra-fine metallic pigments that, as the solvent evaporates, align perfectly on a smooth, non-porous surface. This uniform pigment alignment is the technical secret to its reflectivity, creating a continuous layer that mimics real chrome. The Gorg Mercury Chrome Paint 100 is the ultimate liquid chrome paint for writers seeking a high-impact, reflective tag.
Full Metal Paint™ (FMP): For Drip Tags with a High-Gloss Finish
Full Metal Paint is a high-viscosity, pigmented paint designed for maximum opacity and a full, glossy finish. Its thick consistency makes it the best refill for Grog Squeezer™ markers, as it allows you to create thick, controlled drips without being too runny. Unlike inks, FMP covers the surface completely, making it highly effective on dark or already-painted surfaces. The Grog Full Metal Paint 200 is the go-to paint marker refill for writers who demand a solid, vibrant, and durable line.
Buff Proof Ink™ (BPI): The Ultimate Staining Ink
Buff Proof Ink is the original Grog formula that built the brand's reputation. This alcohol based ink is a dye-based solution, meaning the color is fully dissolved, resulting in a low-viscosity fluid that deeply penetrates porous surfaces. Its name comes from its key feature: it is extremely Hard to Buff. The ink stains the surface so profoundly that it often bleeds back through layers of buff paint. This makes the Grog Buff Proof Ink 200 the definitive graffiti ink refill for long-lasting tags.
Street Killer Ink™ (SKI): Unmatched Black Permanence
Street Killer Ink is the most aggressive ink in the Grog lineup. It takes the staining concept of BPI to its technical limit. This deep black, alcohol-based ink is formulated for maximum penetration on an even wider range of surfaces. For whom who want to push its performance even further, the Grog Booster 08 SKI powder can be added to the Grog Street Killer Ink 200. This additive increases the pigment load, enhancing the ink's opacity and staining power for the ultimate in permanence.
Xtra Flow Paint™ (XFP): Engineered for Grog Cutter™
Xtra Flow Paint is an alcohol-based paint specifically engineered for valve-action markers. Its key technical characteristic is its perfectly balanced, low viscosity and finely milled pigments. This fluid, fine-milled formulation ensures smooth flow through the pump mechanisms of Grog Cutter™ and even through dense felt tips, without clogging, providing a constant and reliable output. The Grog Xtra Flow Paint 100 is the official refill for these markers, designed to deliver sharp, opaque lines with every stroke.
