The impossible restoration is here! Can this 1975 Tonka Grader ever look new again?! Watch this awesome toy restoration video to find out! I start with the most trashed Tonka toy I could possibly find. After a little research I discover that this is actually a 1975 Mighty Tonka Road Grader, Model # 3945. Spoiler alert, I talk through the first part of this video. If that isn't really your thing, feel free to fast forward to 5:33 to avoid all of the talking.
