DIYMAG Blank Car Magnets — 2PC 17 x 12 in Printable Vehicle Magnet Signs, 25 mil Strong Hold

If you need temporary, reusable vehicle signage or a quick way to conceal an existing badge, the DIYMAG 2-piece 17 x 12 inch car magnet set offers a printable vinyl surface bonded to a strong 25 mil magnetic backing. These magnets arrive blank and white so you can print logos, contact details, or custom graphics using compatible inks, then stick them securely to ferrous vehicle panels. Rounded corners and a flexible construction reduce edge catching and make them simple to apply, remove, and reuse without harming paint when used correctly.

How secure are these magnets at highway speeds?

DIYMAG magnets are built with a reinforced magnetic backing and a 25 mil thickness to maximize adhesion to steel surfaces. When applied flat to clean, smooth ferrous metal they resist lift and remain stable at normal highway speeds; proper surface prep is essential for best performance.

• 25 mil magnetic backing for strong hold
• Rounded corners reduce edge flip-up at speed
• Works only on ferrous metal — not aluminum or plastic
• Press flat and smooth to eliminate air pockets

Can I print my logo or artwork on these blank car magnets?

Yes—these white vinyl-faced magnets are inkjet printable and accept solvent, eco-solvent, and latex inks, as well as permanent markers. That makes them a flexible choice for short-run branding, seasonal promotions, or field identification without buying permanent decals.

• Printable vinyl front layer for crisp graphics
• Compatible with solvents, eco-solvents, and latex inks
• Can be trimmed to custom shapes with scissors or a craft knife
• Good for temporary vehicle branding and event signage

Will these magnets damage my car’s paint or leave residue?

When used as instructed—applied to clean, dry ferrous metal and removed regularly—these magnetic sheets are designed to avoid harming paint. They can protect the underlying surface from small scratches and dings while serving as a removable cover for factory badges or exposed logos.

• Non-adhesive magnetic backing means no sticky residue
• Removable and reusable without adhesive removal chemicals
• Should be stored flat when not in use to retain shape
• Not suitable for non-ferrous surfaces like aluminum or fiberglass

How do I apply and care for the magnetic signs?

Clean the metal panel with mild detergent and dry completely before applying the magnet. Press the magnet flat from the center outward to remove air pockets; remove periodically to clean both the vehicle surface and the magnet backing to maintain adhesion.

• Clean surface with soap and water, then dry thoroughly
• Flatten magnet onto panel, smoothing toward the edges
• Remove and re-seat occasionally to prevent dirt buildup
• Store flat and avoid folding to preserve magnetic strength

Who is this for? DIYMAG’s 2-pack of 17 x 12 inch blank car magnets suits small businesses, tradespeople, event staff, and anyone who needs temporary vehicle identification or a removable way to hide factory logos. Designers and makers who print custom graphics will appreciate the printable vinyl face and the ability to cut magnets to bespoke shapes. If you regularly switch vehicles or need seasonal signage without permanent changes, these magnets give a fast, reusable, and paint-safe solution—provided they are used on ferrous metal panels and cared for as recommended.
