I have been using the 'Gold' but can;t find it locally. Is it the best? I also use the polish and yellow wax.

Does the Parts Shop carry it?

I have been most impressed with the Gold Class car wash. I have never seen my car shine so much just from a wash. I also use the Gold Class wax, and it works just as well.
I have used other Meguiars car wash solutions, and they work very well. I actually just went to buy more gold class this weekend, but pepboys didn't have any, so I just bought another generic brand of meguiars for the time being.
They all work very well, but I definitly recommend Gold Class.

Yes, I use the "Gold Class Car Wash Shampoo & Conditioner" and it is awesome. I also use the pink bottle "soft wash gel", but have switched to the gold class. I get it at G.I.Joes in seattle. I can also get them at my local Shucks and Al's auto supply.

If you still can't find it, I will give you some online stores to buy it from
