My My son was moving some paint in a jar to the garage. Next thing I know he returned with his new jacket sleeve and more covered in silver metalic paint. I said, give it to me and I'll see what I can do. In despiration I grabbed the WD4D and wa-la It started coming off! Before I knew it it was back to normal. Leaving two very happy people. I'll tell this one for years to come! He loves that jacket!
