Have used the product for a couple years. No need to try something else, it works great on glass.
Gets the job done just wish there was a bigger bottle.
I would recommend this DC product and the ease, low cost shipping and affordability of AquaLab
Works very well
I’ve used dark crystal clear for a few years now and have never looked back. My banger still looks brand new even after at least a thousand dabs. Got the dropper bottle for on the go. Best ever!
