Hi Renton,agree with Ben, the powder coaters normally use a high temp blue masking tape. How old is your frame? My 2010 Turner has grease nipples that screw in, some earlier ones are push fit. If there is a slot in its a clue. They And all the plastic bushes MUST come out before powder coating. The heat will melt the grease which will contaminate the finish. The bottom bracket,headtube,seat tube and all the bush faces (frame and swingarm) need masking. The shock mount areas are Ok without. The colour is up to you, wanted a light blue on mine but they didn’t have it so went for yellow which looks sweet. Thought about new decals? If I had it done again I think I would have it clear lacquered as well. Can Email you some pics if you want :-) if you want any more help give me a shout
