bruce- that's correct. i use it as LSP (Last step process) to get the extra boost in depth and shine. but since i dont dd my Z i dont need to use traditional waxes. the SpeedShine has enough wax that it gives a very nice protectant. boost it with SprayOn Wax and it's a very strong protectant (until next wash).
also sprayon wax is a great protectant to use on the front bumper making bug removal easier.
final note on the waxes from Griot's. it's got great water beading power great for QD. i prefer polymer on my dd as it sheets water off the panels.
