Check boatersworld.com or westmarine.com . They both sell it . It runs around 30-60 bucks a quart . I use it on the wood on my 46ft boat and it will shine like glass as long as you put it on correctly !! I also use it on my r/c scale boats . Oh and make sure you get glossy . It will come in other finishes too.
