Why NOT restore them? Most of us run across early rough die cast cars frequently, and they can most likely be purchased for next to nothing because most sellers have been conditioned to believe that because restored toys are basically worthless, then toys that need restoring are worse than worthless. Well guess what...properly restored toys are now selling very well online. And its not that hard to to turn these below on the left, into those on the right. Yes, they are the same cars. The truck was restored at the same time.
To start with, here's what you'll need to begin your restoration project. A few basic tools, a dremel tool, oven cleaner, rubber gloves, matching paints, a waterproof work box, a toothbrush, a couple coat hangers, and some 100 grit and 400 grit sandpaper. We also suggest having some correct replacement tires on hand before you begin the project (most are available online). Begin by spraying the toys thoroughly with the oven cleaner, then allow several hours for it to work (do not hurry it).
