The USC 26006 Icing 24 oz tube is a glazing and finishing filler putty designed for smoothing and perfecting auto body surfaces after the main repair work. With a strong customer rating of 4.8 out of 5 stars from over 900 reviews, it indicates good user satisfaction. This putty is known for its fine consistency, making it easy to spread and feather out thinly, which is ideal for filling small imperfections and creating a smooth surface before painting.

It typically cures quickly, allowing for faster sanding and overall repair time. Its sandability is a strong point, as it sands to a smooth finish without clogging sandpaper.
