Tim thanks a ton for doing the wash, it pretty much proved my point that a glaze can not be "sealed" in. IMO the darkness that is left over on the PB is probably from the natty's blue and not the glaze.
BTW nice job on the engine :dblthumb2:
Just think of those people who "clean" paint with CG EZ-Creme Glaze then apply a sealant over top :laughing:.
