Product Information
Full details
Max Meyer HP Primer Multigrey Extra is a high-performance, high-build primer tailored for professional automotive refinishers who require a reliable and efficient foundation for topcoat application. Its primary benefit lies in its exceptional build capabilities, quick drying time, and ease of sanding, which significantly improves body shop workflow efficiency. However, users should note that as a professional-grade automotive product, it requires proper spray equipment and safety protocols for optimal results, making it less suitable for casual DIY repairs without the correct ventilation and spraying tools.

FAQs
Is this primer ready to use out of the can?
No, it requires proper mixing with the appropriate hardener and thinner according to the technical documentation.
Can this be used on plastic bumpers?
While it is compatible with many substrates, you should verify if an additional plastic adhesion promoter is required for your specific bumper material.
What is the primary benefit of the white M1 shade?
The white shade provides better coverage for light-colored paints, which helps minimize the number of topcoats required.
Does this product require a topcoat?
Yes, this is an undercoat primer and must be sealed with a compatible topcoat or clear coat for UV protection and durability.
Can I store the remaining primer in the 3L container?
Yes, ensure the lid is sealed tightly to prevent air exposure and store in a controlled environment to extend shelf life.
What equipment is recommended for applying this primer?
A standard professional spray gun, such as an HVLP system, is recommended for the best atomization and build.
Troubleshooting
Primer is too thick during application
Check mixing ratios and ensure you are using the correct recommended thinner for ambient temperature conditions.
Poor adhesion to the substrate
Ensure the surface was sanded with the correct grit and thoroughly degreased prior to application.
Sanding creates excessive dust or clogs paper
Verify the primer has fully cured for the recommended duration; humidity and temperature can influence total cure times.
Pros and Cons
Pros
- Significantly reduces prep time due to fast drying and easy sanding
- High-build quality covers minor surface defects effectively
- Bright white M1 shade aids in achieving accurate color match for light topcoats
- Consistent, professional-grade results across various substrates
Cons
- Requires professional spray equipment for proper application
- Strict ventilation and safety measures needed due to chemical composition
- Volume size (3L) is optimized for high-volume shops, potentially excessive for single-panel repairs
Setup, Compatibility & Care
To achieve professional results, ensure the surface is properly degreased and cleaned before application. The product is intended for use with HVLP or conventional spray guns, following the technical data sheet for the correct mixing ratio of primer, hardener, and thinner. Always wear appropriate personal protective equipment (PPE), including a respirator rated for organic vapors and safety glasses. After spraying, clean your equipment immediately with a compatible solvent to prevent the primer from curing inside the gun fluid passages. Store the 3L container in a cool, dry area with the lid tightly secured to maintain the integrity of the material for future use.
