DIYMAG Blank Car Magnets — 4-Pack 24x12 in Printable Vehicle Signs, 40 mil Durable

DIYMAG Blank Car Magnets are a 4-piece set of 24 x 12 inch printable, reusable magnetic vehicle signs designed to attach securely to ferrous surfaces for custom branding or temporary logo coverage.

These magnet sheets turn any compatible vehicle into a removable advertising surface or a temporary cover-up when you need to hide factory badges or company logos. Each panel is 24 x 12 inches, 40 mil thick, and finished with rounded corners to resist peeling during drives. The white printable vinyl face accepts solvent, eco-solvent, latex inks or long-lasting permanent markers, so you can create professional graphics at home or with a print shop. They’re intended for use on steel or other magnetic metals only — they won’t stick to aluminum, plastic, fiberglass, or painted surfaces with weak adhesion.

How well will these magnets stay attached at highway speeds?

These magnets are engineered with reinforced magnetic backing and a flexible face to maintain strong contact with a clean, flat steel surface. When applied correctly, they resist lifting and corner roll even when driving at faster speeds.

• 40 mil thickness for a durable, stable bond
• Rounded corners to prevent edge curling in wind
• Best adhesion on clean, smooth ferrous metal panels
• Reapply and realign easily without adhesive residue

Can I print my logo or design on these magnet sheets?

Yes — the front is a white inkjet/printable vinyl surface made to accept a range of inks and markings. Use compatible solvent, eco-solvent, or latex inks for durable outdoor graphics, or mark temporarily with permanent pens for quick labeling.

• Printable vinyl face for sharp color reproduction
• Compatible with common wide-format printers and inks
• Also suitable for hand-cut shapes or stencils
• Designs can be printed professionally or DIY at home

Will these magnets damage my vehicle’s paint or finish?

Magnetic signs do not use adhesives, so when used as directed they won’t leave sticky residue or remove paint. Proper surface prep and careful removal minimize the risk of dirt scratching or moisture trapping beneath the magnet.

• No glue or tape — reduces risk of finish damage
• Always clean and dry the application area first
• Remove periodically to inspect and prevent moisture buildup
• Store flat when not in use to preserve shape and magnetism

How can these magnets be used beyond vehicle signage?

Beyond covering logos and promoting your business on cars, these flexible magnet sheets are versatile for temporary signage, trade show displays, or protecting surfaces. They can be trimmed to custom shapes to act as protective patches or temporary labels around the shop.

• Cut to size for temporary branding or directional signs
• Use as removable protective covers over vulnerable areas
• Ideal for rental vehicles, fleet swaps, and pop-up events
• Reusable across different vehicles or metal surfaces

Who is this for? DIYMAG 24 x 12 inch blank car magnets are ideal for small business owners, contractors, real estate agents, event vendors, and anyone needing temporary vehicle branding or logo concealment. They suit do-it-yourself printers and sign shops who want printable, reusable panels, plus drivers who need a non-permanent way to display contact details or promotional graphics without committing to permanent decals.
