This stuff is a polishing agent. It will wear down the finish on your musical instrument over time. If your instrument has been scraped right down to the wood, then this product is likely a poor fit for your needs. OTOH, if you want to really spruce up the shiny bits, Bellacura Polish does the job extremely well. I am very careful with my musical investments, but cosmetic scratches can't be avoided if you're actually playing. This polish eliminated years of that in one application. For me, this is an easy 5-star rating. YMMV
