B39 Mineral Grey Metallic Touch Up Paint Kit - Platinum Repair Kit

In this review the B39 Mineral Grey Metallic Platinum Kit is evaluated as a practical DIY solution for small blemishes on BMW finishes. The bottom line: this combo kit is best for car owners who want an exact color touch up without a body shop visit, because it packs primer, colorcoat and clearcoat plus accessories into one package that covers at least 10 square inches. The review focuses on ease of use, color accuracy and the included tools so readers can decide if this kit suits their repair needs.

Key Features

• Complete combo: The kit includes Automotive Primer, Colorcoat and Clearcoat so users can perform a full multi-layer repair without buying extra materials.
• Color Match Guarantee: The formulation is intended to match BMW B39 Mineral Grey Metallic, reducing visible differences when applied correctly.
• DIY-friendly applicators: User-friendly brushes and a combo applicator make it possible for one person to manage small chips and scratches with minimal experience.
• Low-VOC Colorcoat: The paint and clearcoat are low-VOC, offering a more environmentally conscious option compared with many workshop paints.
• Accessory kit: Sandpaper, wax and grease remover wipes and polishing compound are included so the surface prep and finish polishing can be done in one session.
• Coverage: Each Combo covers at least 10 square inches, which is sufficient for multiple small repairs on a single vehicle.

Who It's For

This kit is aimed at BMW owners and DIY enthusiasts who need a precise touch up for small chips, door dings or scratches and prefer to avoid the cost and time of a professional repair. It suits those comfortable with basic surface prep, layering primer/color/clear and following test card instructions to verify color before committing to the repair.

It is less appropriate for large structural repairs, rust remediation or for users who expect a perfectly invisible repair on complex panels without practice. Anyone who struggles with consistent paint flow or prefers guaranteed shop-level results should consider professional refinishing instead.

Pros & Cons

Cons

• Some users report occasional paint consistency issues such as clumping, so careful testing and technique are required.
• Coverage is limited to small areas (about 10 square inches), so larger panels need more product or professional attention.
