Will Self-Adhesive Magnetic Warning Light Bars Adhere to Aluminum or Fiberglass?

Question:

Will these self-adhesive magnetic mounting plates and here to my fiberglass truck topper the same as it says it will adhere to the aluminum body of the truck cab?

I have a great alternative to the Blazer Amber Warning Light Bar # C4850AW. After some research, I confirmed that the Blazer Amber Warning Light Bar will not attract to aluminum or fiberglass. However, I recommend purchasing the Peterson Amber Revolving Halogen Warning Light Bar # 761A. Instead of mounting with a magnet, the Peterson permanently mounts on the installation surface and plugs into your vehicles auxiliary outlet.

If you are looking for a no-drill solution with a bit of a different design than the Peterson Light Bar, I recommend the Custer 40-LED Light Bar w/ Controller Box # STR-40-S. Even though the magnetic mounts won't work on the Custer, the bar will still be able to attach using the suction cup attachments. The Custer installs into your vehicle's 12-volt system.
