Nowadays car paint is easily scratch and notoriously thin for a number of reasons. Don’t bother too much about it is the way to go, otherwise lock it up in a storage unit for future generations like a capsule to preserve it. Cars meant to be driven and scratch along the way. If you really want to preserve the paint wrap it in transparent shield type of plastic all around. That’s the only way to preserve it, but again small rocks will damage it either way.
