See, what had happened was...
I've seen the dip getting peeled off, If you like it, how long does it stay good, and how easy is it to scratch?
As long as it's applied thick enough / correctly, you can leave it on forever. However, some recommend peeling it once a year and re-doing it.
I wouldn't say it really scratches, but it'll get a "mark" about as easy as paint does.
