If you are follower of tech blogs (or used to follow them) a few years ago, you probably saw a video of some college researchers who had invented a spray on coating that would allow you to use your iPhone under water. That team partnered with Rustoleum and you can now buy that little science project at your neighborhood Home Depot. I did just that.
I bought the cans a few months back and haven’t thought of anything I’d risk spraying it on. And for $20, simply spraying it on objects for fun could be a costly endeavor. Long story short, I just sprayed my grill yesterday and it seems to work well.
I had issues with rust spots on the stainless top and simply wiping it down would still leave it damp, i.e. bad. Time will tell if the coating will hold up with the high heat of the grill. As you can see from the video, it does the job, but it leaves a very
clear noticeable film on the surface. I peeled off the film on the temperature gauge so you could get an idea of what the coating looks like.
It’s definitely not magic (no way I’d spray it on an electronic device), but it’s still cool.
