A quick question concerning the renovation of paintwork on a 2012 trad.

The paintwork is in reasonable superficial condition but is slightly rough to the touch. I would like to improve the paintwork for long term ownership and I think my options are:

1 Clay bar the surface,
2. T Cut the paint or
3. Use polish

I have no experience of clay baring but have used T Cut to good advantage in the past. Following any of the above options I would use good quality wax to protect the paint surface.

Any advice on the way to go would be much appreciated.
Bob.
