Looks like a wet sand and clear prospect. Best get someone who has done it before do it for you, or help through it all.
Don't want to sand through any of the layers seeing you have many colors and some may be thin. Other than the few
scratches that go through the paint, she will look great with a coat of clear. Again, do you know someone with a shop?
Other wise the cost maybe more than your willing to spend. Got a budget in mind?
If you want to spend the least, go with buff and polish... she'll still look good and save money for the Motor
