I love gold leaf with a back shadow and love the idea of doing a car up with vintage style lettering if you plan on keeping it. If unsure, vinyl is an option and you can also create gold foils in that as well.
Funny I couldn't remember where that line loc was sold to or who got it. I wound up needing a few things for this yellow car that I had previously sold as extras and ended up having to buy some items again. Luckily, I found another vintage line loc kit on eBay. I remember telling myself, you may need that some day! nahhhh! lol
Can't wait to see what you have collected.
