I have been using for over a year .. look no further than is the cleaner guitar of references (not just guitar, all intruments with satin varnish it dlicat or gloss).
Having the Beach test a product: dunlop, d'addario and so on ... all have a tendency to remove a thin layer of varnish, we must give several times to remove fingerprints and fat. In addition, they n'liminent not scratch marks or other small CLAT.

And here's what appeared on Fender Meguiar's care kit: unlike all the products I have tried this product not only of isa remove a layer of varnish but dissolved and partly fills the "gaps" by providing a rsine. What enlve small scratches, and complements all traces of fat. The more j'adorre is that the product is parhfum strawberry (or similar), like other products.
In the other there is the polish for the finishing and the product between the two that prpare this polish. As I said, I use the product once a week (that's enough, the more I deprecated) and my stratocaster is like new (we often make me rflexion, although it did three years and had a lot of bars and other scne).

I put a 9 because the product is a bit expensive and must be renewed every year for the economy or every 6 months
