My kid has a car with one of those bumpers, not sure the exact wording. Anyway she has a small gouge in it maybe 3/4 inch round and 3/8 deep, obviously showing a blackish color that stands out against the bumpers gray/silver paint. Naturally she has no idea how it happened. I'm sure I could fill it and just touch up that paint so it did not stick out like a sore thumb. Anyone know what to use as a filler? I was actually thinking just some paintable silicone caulk would bond well, smooth easily and take the touch up.
