Lost one of the engine badges from my R90S today. Fortunately these things are still available, or at least aftermarket versions are, at a princely sum of £48 each! Obviously I don't want to make a habit of losing these therefore which glues might be recommended for sticking these back in place? I'm aware that alloy is notoriously difficult to stick things to. Paint needs to be self-etching acid based but what about glue? Any advice appreciated.
