3M Adhesive Metal Disc 4 Pack
3M Adhesive Metal Disc for Magnetic Mounts – Fibreglass & Aluminium Ready
Mounting a magnetic mount or antenna to a non-metal roof? This 76mm 3M adhesive-backed metal disc gives magnetic bases something to grip to — even on fibreglass, aluminium, or composite panels. Whether you’re installing a Starlink dish, GPS puck, or LTE antenna, this disc creates a magnetic-friendly surface with no drilling required.
⭐ ESSENTIAL BENEFITS
- Gives magnets a place to stick – Ideal for fibreglass pop-tops and alloy canopies
- Strong 3M VHB adhesive – Sticks securely to flat, clean surfaces
- Perfect for Starlink, GPS & LTE antennas – Works with all magnetic mounts
- Weather-resistant – Built for Aussie road, weather, and heat

⚙️ HOW IT WORKS
Just peel and stick to a flat surface — fibreglass, aluminium, polycarbonate, or painted timber. Once bonded, the disc acts like steel and lets your magnetic mount snap on just like it would to a car roof. No screws. No brackets.

⏱️ ADHESIVE CURING ADVICE
To ensure a secure and permanent bond, the 3M adhesive must be left undisturbed for a full 24-hour curing period. This allows the VHB adhesive to chemically bond to the surface and reach maximum holding strength.
- Install only to clean, dry, and flat surfaces
- Apply firm, even pressure for 30 seconds during installation
- In cold conditions, gently warm the surface beforehand to improve adhesion
⚠️ Failure to wait 24 hours may result in a weak bond and possible failure.
