Will you be able to see the damage after using UFIXIT DiY Windscreen Repair KitTM?
If you have removed all of the air from the damage, (usually looks like a dark colouring in the glass). You should not be able to see the damage in the screen any more, as the resin has the same opaque and refractive value as the glass. You may be left with a slight white mark where the impact point was.
