Garage project: rebuilding the old Civic with my 10 year old
My son asked to help me work on the car and I'm trying to make it a thing we do together. He's not really useful yet but he hands me tools and asks questions constantly. Honestly it's way more fun than working on it alone. We're probably going to be working on this thing for years but that's kind of the point I think.
How far into the rebuild are you? The key is making it fun first and useful second. Break it into small wins he can feel good about.
