I purchased this product to etch on class using a stencil. The product does not etch as opaque as I would like, but I do not know of a product that does.
I got this product to frost some glass lamp shades. I had to repeat the process a couple times, but it does what it says. It does etch in the pattern that it's painted on (like brush strokes), so be aware of that. But I really appreciate this product, since using this is much easier than trying to sand the glass to get a frosted surface! I definitely recommend it.
