My first woodworking project with my 12 year old grandson. He and his Dad are big superhero fans. The Batmobile was built from plans from https://www.lloydswoodtoyplans.com/. There are 12 parts to the body. Each part is 1/2” thick plywood and were profile cut on my CNC machine. They were glued together followed by lots of sanding and several coats each or sealer, primer and latex spray paint. We used Bondo body filler to make it smooth.
