This product can repair curb damage, chips, scrapes, scratches etc., but can't repair broken or out of shape
wheels.
The repaired area may vary slightly in color from your original wheel, but the difference will be minimal and  should only be visible upon close inspection. There may also be slight differences in color between the new  paint and your original paint.
The filler is specially formulated to bond fully with aluminum and alloy wheels. It will never come off, even
with vibration at high speeds. Its density is the same as that of the wheel material, so it does not need  dynamic balancing after repair.
