I'm fairly new to all this also. What condition is the car in? If it needs a correction that may not be enough. If it is just a little dirty/dusty from being in the garage that sounds perfect.
I have been getting my 72 Jimmy ready for some up coming cruise ins and shows and I did a machine polish, machine sealant, brilliant glaze, and topped it with Americana and it really POPS right now!!
Dont forget the trim, interior, and glass as those little details really help a vehicle stand out.
