I wish my ISP would let me link larger pictures to show the depth of shine on my '96 Z3. This was done by an old favorite, a bottom layer of 3M Imperial Hand Glaze and a top coat of Collinite Carnuba. I love this combination for the shine but want something that will last longer per application. I have an order of Z1 and Z2 on the way and from everyone's excellent advise hope the combination gives me this depth of shine but a little more durability. BTW-This car has the X-Pel Clear Bra installed, pretty invisable I'd say! ..Thanks...Michael P.
