Meguiar's Pro D300 DA Microfibre Correction Compound — 1 gal concentrated, low-dust no-sling high-gloss finish

Designed for use with dual‑action polishers and Meguiar's DA Microfiber cutting discs, this 1‑gallon concentrated formula uses super‑micro abrasive technology to attack scratches, swirl marks, light oxidation and acid rain etching without excessive dusting or sling. The low‑dust, no‑sling blend wipes off clean and extends working time so technicians and enthusiasts can correct panels efficiently and produce consistent, high‑gloss finishes.

How does Pro D300 remove scratches and swirls effectively?

The formula employs super‑micro abrasives that abrade microscopic paint defects while preserving surrounding gloss. When paired with a DA Microfiber Cutting Disc on a dual‑action polisher, it balances cutting power and finishing ability to reduce the need for multiple steps.

• Super‑micro abrasive technology targets light to moderate defects.
• Optimized for DA microfiber pads to avoid holograms.
• No‑sling, low‑dust formula for cleaner work areas.
• Concentrated gallon size lowers cost per vehicle.

What equipment and pads should I use for best results?

Meguiar's Pro D300 is made for dual‑action polishers like the MT300 and is best paired with DA Microfiber Cutting Discs or DA Microfiber Xtra Cut Discs for more aggressive correction. Using the correct pad and machine keeps the process safe for OEM glossy paints while maximizing efficiency.

• Use with a dual‑action polisher (recommended MT300).
• Choose DA Microfiber Cutting Disc for standard correction.
• Select DA Microfiber Xtra Cut Disc for heavier defects.
• Work at manufacturer‑suggested speeds and overlap passes.

How easy is it to apply and remove the compound?

The compound is formulated for prolonged working time and effortless wipe‑off, making panel refinement faster and reducing the risk of residue build‑up. Its low‑dust, no‑sling nature means less surface prep and quicker cleanup between stages.

• Longer working time for easier buffing and blending.
• Cleans off with minimal residue using a microfiber towel.
• Low dusting reduces pad and shop cleanup.
• Suitable for multi‑panel correction without re‑application hassles.

Will Pro D300 harm factory paint or clear coat?

This product is engineered for safe use on all OEM glossy finishes when used as directed. Correction power comes from micro abrasives and proper pad/machine selection, not aggressive chemicals, so following recommended procedures preserves paint integrity.

• Safe for OEM glossy paints when used with DA systems.
• Use appropriate pad density and machine settings.
• Test on a small area before full‑panel work.
• Follow up with finishing polish if needed for ultimate gloss.

Who is this for? Pro D300 is ideal for professional detailers, body shops and serious enthusiasts who need an efficient, cost‑effective correction compound in larger volumes. If you run a detailing business or perform frequent multi‑panel corrections, this 1‑gallon concentrated option delivers repeatable, high‑quality results when used with Meguiar’s DA microfiber systems.
