I originally wanted to use it for the inside of the kid of this vintage suitcase remodel. Unfortunately, I discovered that is wasn't strong enough. I knew it was a shot in the dark, but was still disappointed because I so wanted it to work!
On the can, it explains that the more layers you use of the magnetic spray paint, the more magnetic the surface would be. While I was skeptical that it would work for my purpose, I thought perhaps it might work okay considering I used an entire can on an area that was 12" x 15". Of course, I was wrong.
In their defense, they do advertise this spray paint will work best with lightweight magnets, light these poetry magnets, and it did. The magnets I wanted to use in my projects were small containers that will hold craft supplies.
The magnetic paint is a grey color, just like primer. It can be top coated with another color of paint if you like. I used it 'as-is'.
Although I was disappointed the magnetic paint wouldn't work for my purposes (it did work as they specified), that wasn't my biggest disappointed. My biggest disappointment was what a pain it was to apply this paint.
To cover my small item, I found myself vigorously shaking the can almost non-stop. It would only spray for a few seconds before it quit , and I would have to shake it again and again and again. It didn't matter what I tried, it seemed to need almost constant shaking. It took more of my time to shake the paint that it took to paint the item!
The bottom line is this product does do what the manufacturer promises, it does create a surface that lightweight magnets will stick to. You just have to have a lot of patience while using it. Make sure you use it in a very well ventilated area and follow the directions on the label when it comes to drying time.
