I have an FRP boat (let's just pretend it's a Merlin)

It has been suggested that I rub it down with 1200 grit and run it over with a car body polisher.  Is this a good idea and should I rent a buffer to do it with, also, what kind of polish would be best?  Could I mess my boat up?

Wow - got time to do a quick google and struck gold

G6 car poish but be careful.

All over with Polishing compound, (3M DO A GOODUN), then a coat of any good car polish. then buff! zap.

You can buy buffers for around a �10 now...Hardly seems worth hiring...
