With all of Meguiar's fancy waxes, I think many forget about Cleaner Wax. I've been practicing my detailing skills on a lot of friends cars and have been getting absolutely fantastic results with the paste version of Cleaner Wax applied by hand. I also recently applied some of the liquid version to a friends car with a DA and also got incredible results -- and the product is the cheapest wax in the entire line!
The downside is that I find it to be lacking in the durability department, but I have been very happy with it so far. You can get great results with very little work with this product, and I think it produces very nice results for the price.
