After 3 days working on the garden with the wife, I had a bit of bike tinkering time. My old GT Timberline (my first proper mountain bike) has been looking rather sorry for itself lately with more surface rust appearing every time I look at it. So the time came for a strip down. The question is, do I lightly sand and treat rust then wax or clear coat to keep the "patina", or full respray and graphics. Appreciate the frame is not that exotic, but having owned for 25 years sentimental value is high.
