Have you tried your local Body Shop supply outlets? If they do not have these products they can normally get them in a day from their local Meguiar's distributor.
You also might try the Autopia Store (http://www.autopia-carcare.com/index.html ). I think DavidB carries the Meguiar's line and he is located in southern California.
I agree with JBM, I tried some #7 on a Lexus this weekend and for some reason after I removed with a microfiber, I got some holograming. I immediately stripped it off and used #83 to take it out. I also noticed no difference when I used it. Just my opinion though.
I order my stuff from autopia.com I believe they are located down by you so shipping should be real fast. I'm in LA and get my order within 48 hours max.
