Bests & Worsts Reviews from Amazon

I bought this spray-on product without great expectations, but I was pleasantly surprised by its ease of use. While its best to try to spray as even a coat as possible, small inconsistencies can be overcome with a second spraying (in fact, more than one coat is probably going to be necessary in most cases, since just one layer is too transparent and will show inconsistencies). My photo was taken of a piece of old glass, partially sprayed, and layed against a window with a view outside. On the far left, you can see the opaqueness with two quick sprays. The far right shows the glass unsprayed. Toward the middle, you can see the unevenness of one coat. I did this test quickly -- with more attention, I could have achieved a better result. The product has really awful fumes, but since I was only spraying a few 10" x 15" glass panels, I was able to spray each layer while holding my breath. I live in a NYC apartment building, so spraying outside was not feasible. I did the job in my bathtub - with the window open - , using an old plastic shower curtain liner as a backdrop in case of over-spraying. The pinhole release on the can however, was quite accurate, and did not spray more than an inch or two beyond the intended area (holding the can about 12" from the glass surface). Stay Safe - Always wear protective eyewear. I wore a pair of disposable gloves too. After each spray, I quickly left the bathroom, closed the door, and waited thirty minutes before applying another layer. The odor remained noticeable in the bathroom for several hours. However, the glass panels retained no odor after they had dried. Those with pulmonary concerns should probably consult the directions carefully. Definitely not for use/storage around infants and children in my opinion.. A few days later, I wiped a panel with a water-dampened cloth--nothing came off on the rag, and after the glass dried, the opaqueness seemed unaltered. However, I'd be careful about using stronger glass-cleaning products without testing first. Also, My result is on real glass. Don't know how it would work on plexiglass-type products. Maybe others have commented?
