Well, so far I haven't gotten any proof from TT that 100 grit etch is ok and I haven't gotten any proof elsewhere that it is not. So I guess I will have to draw my own conclusions once I see the results of switching to a higher grit for the "etch" ie: shine removal. If I can get away with using the product in a healthier manner for the nail then that would be great! :green:
Hiya x.. I think you can see the proof for yourself. use a 100 grit on your own natural nail...then a 240....you will see the proof....
