i have some gummy stone we use in the ski industry to polish out edges I start with those to get the heavy work done quick, then I used marcus from rcshox trick of lighter fluid and 2000 wet dry and rubbed em till my fingers were sore and they were shiney smooth. You need to get ahold of marcus and get some of his 2 stage shock pistons and g discs . The best upgrade per buck you can do on your rig.
