im not sure where you are from, but where i live i go to like lowes, home depot, autozone, wal-mart for the fiberglass... the lycra material you can get at any fabric store, the wood rings, either make them or buy them online, the bondo should be bought at an auto specialty store... i used auto-zone bondo and it cracked within a week, did it over with Rage bondo and it has held for years... i can show you some of my product if you are interested
