I own a lot of topcoats and I have to say, this one is in my top three. I did a scratch test on it to see the difference between drying indoors and curing in sunlight...this stuff is tough whether you expose it to sunlight or not, but it definitely turns into an armor of sorts with exposure to sunlight! The nice thing is that it still comes off easily with a good remover (I use theirs!) even after it has been hardened in sunlight. Tip: I found that this topcoat looks its best when applied with a floating technique. If you apply pressure and use too many strokes, you’ll create brush lines in it; this is true for many topcoats. Be gentle. It’s self-leveling and will look flawless with little effort on your part.
I’m very happy with this product. It’s really amazing.
