Zaino is my protection of choice. My son uses it on his 02 Firehawk & 68 Firebird and now it's on my Crossfire. It's more than just a polish - it protects the paint from most anything. Bird-doo just slides off, road tar wipes right off. Once you get 3-4 coats of Z2 on you're done. Just wash with their carwash & spray with their detail spray for the next few years. It's a little costly up front but the protection and ease of maintenance makes up for that IMHO.
