Does anyone have or can anyone do a side by side shot of polish before and after it's flashed. I'm getting ready to do my big spring detail in a week or so and last year this is the only thing I really struggled with (not knowing how long to work the polish). When I polished before, it seemed as if the polish was transparent and 'greasy' looking almost immediately so I never really saw where it flashed or changed consistency. I think a lot of people could benefit from this. Thanks!
