People collect the old phones today also, which drives the prices on those up rather drastically. I was quite shocked to see what was out there when I started looking for plastic. Best place to find the older phones is your local re-sale .. value village .. Salvation Army stores.The virgin plastic MUST come from the actual slot car body in the color you desire, although some people have matched colors using the old 1960-'s-70's style Plastic colored Telephones !
Soooo... you need to collect slot bodies (or phones) to use as donor plastic for your goop !
Well, I failed at it. For a coupla reasons.Can you do molds, or make products with goop?
