I rarely write reviews and I am not a professional detailer. Polymer Net Shield was VERY easy to apply (I used a damp microfiber and sprayed the towel then applied over a roughly 3' x 3' area making 3-4 passes over the entire area, then buff off with a clean microfiber). I'm not sure why people had a hard time removing it, I had some that I missed and I was easily able to buff it off by hand over 24 hours later. This car ('11 Maxima w/ Crimson Black Metallic paint) hasn't had treatment in over 3 years. I washed, clayed, applied Net Shield and it looks great, nice mirror finish and it seems to make minor scratches less visible. I applied to the glass and plastic as well. Made the plastic around the wipers look brand new. Water shedding is GREAT, drove from Missouri to Florida thru Hurricane Nate with the wipers off (most of the time). It will be completely dry after 10 min. of driving at 45 - 70 after being rained on all day. I plan to apply it to my work trucks as well. Great product and I could not be happier.
