ABRO 5 oz Grinding Paste (GP-201)

ABRO 5 oz Grinding Paste (GP-201) is an essential tool for automotive maintenance, designed to facilitate the precise grinding and lapping of engine valves. This unique product features a dual-grit formulation, providing both the cutting power needed for initial material removal and the fine abrasive required for achieving a smooth, accurate finish. Packaged conveniently in a single tin with separate compartments for coarse and fine grits, ABRO GP-201 offers a versatile and efficient solution for ensuring optimal valve seating and engine performance. Its easy-to-apply consistency allows for quick and effective use, making it suitable for both professional mechanics and DIY enthusiasts. While primarily intended for valve grinding, its capabilities extend to lapping other metal surfaces and removing unwanted burrs, surface imperfections, corrosion, gums, and carbon deposits.

KEY FEATURES AND BENEFITS:

• Dual-Grit System: The key benefit lies in its dual-grit system, which eliminates the need for multiple compounds and streamlines the grinding process.
• Coarse Grit: Efficiently removes material for initial shaping, ensuring a smooth, precise mating surface for optimal sealing.
• Fine Grit: Ensures a smooth, precise mating surface for optimal sealing, contributing to improved engine compression and overall performance.
• Easy Application: Formulated for easy sanding and smooth spreading, allowing for consistent coverage and effective abrasion.
• Industrial-Strength Composition: Ensures longevity and reliability, making it a valuable addition to any toolkit.
• Versatile Use: Extends to lapping other surfaces and addressing various surface defects, enhancing its utility in a range of applications.
• Convenient Packaging: The dual-compartment tin keeps the grits separate and ready for use, minimizing mess and maximizing efficiency.

HOW TO USE:

• Preparation: Ensure the valve and valve seat are clean and free from any loose debris or oil.
• Apply Coarse Grit: Using a small tool or your finger, apply a moderate amount of the coarse grit paste from the designated compartment to the face of the valve. Ensure even distribution around the valve face.
• Lapping with Coarse Grit: Insert the valve into the valve seat. Using a valve lapping tool (either a hand tool or a power tool with a lapping attachment), rotate the valve back and forth with light pressure. Lift the valve occasionally and rotate it a quarter turn to ensure even grinding. Continue this process until a uniform matte surface is achieved on both the valve face and the valve seat.
• Clean Up (Coarse Grit): Remove the valve and thoroughly clean both the valve face and the valve seat to eliminate all traces of the coarse grit paste. This is crucial to prevent scratching during the fine grinding stage.
• Apply Fine Grit: Apply a moderate amount of the fine grit paste from its compartment to the face of the valve, again ensuring even distribution.
• Lapping with Fine Grit: Re-insert the valve into the valve seat. Using the lapping tool, repeat the rotation process with light pressure. Continue until a smooth, polished surface is achieved on both the valve face and the valve seat. The fine grit will remove any scratches left by the coarse grit and create a tight seal.
• Final Clean Up: Remove the valve and meticulously clean both the valve face and the valve seat to remove all traces of the fine grit paste.
• Inspection: Inspect the valve face and seat to ensure a consistent and smooth contact surface.
• Reassembly: Proceed with the reassembly of the cylinder head.
