Morris Minor Owners Club

The bonnet and boot on my 1952 MM convertible have very dull, almost matt, original paintwork (see attached photos). I have tried manually polishing both several times with various polishes (Autoglym, Meguars etc), but the difference is minimal and my fingers ached! The photos show rain spots and it does need a wash, but even so, the paint is much duller than the wings and rest of the car.
I have done some research and it seems a dual-action (random orbital) polisher is what I need but I would welcome any advice on the appropriate tool or brand to use.

I bought one from Argos, a Challenge unit with variable speed. I've used it several times and it does a good job.
You choose the fierceness with hard/softer pads and compound, I've only used farecla G3 compound, which is fine/gentle followed by a G3 wax.
Definitely takes the effort out of the job with good results.
