Any more detailed information about flaws description?
Size of the flaw is measured by 1-2-3-4. In most cases size 1 will come off after car wash and waxing. Size 2 can be removed with cut and polish. Size 3 and 4 would require panel to be painted - however still can mask it with cut/polish and touch up - if you not fused about look of the car. Also, there are some strict auction houses, Like Toyota TAA, Nissan NAA, and Honda - their markings of A1 or A2 will be hard to notice when you look at them car.
Also most marks like A1 or U1 - you would need to get very close to the panel to be able to see it.
Below is a general description.
