Hi everyone,

I've done a search on R4/Super Resurs/Remetalizer but haven't been able to find anything in the forum. From the websites below, this product is marketed as R4 in USA, and Super Resurs in the rest of the world.

Has anybody here heard or used this product before? It got quite some credibility here in Asia and Europe but I still have doubts...
