Car body shop Mops are best, but like Rupert says you need to be really careful not to burnn through the gel.  Make sure the pad is always moist by using a water spray.  They are very expensive to buy so renting one with a sponge head is probably the best option.  I would also be carfeul on classes with thing gel.  The laser is prime for a MOP!

Many of the polishers say "do not use with rubbing compounds" or the like on them. The one I use does, and never had a problem. I think you have to be careful that you don't "burn" the surface by rubbing and rubbing in one place till there is no compound left.

You can compound without a polisher, but you might get tennis elbow in the process.

I put uv protection waxes in the same category as magic beans.
However, the more light you can reflect back the less your gelcoat will have to absorb.
The 2000 owners at my club have all bought top covers with extended sides to cover the blue.
There are dozens of expensive products out there:

Thanks for the tips!

I will try with T-Cut first I think and see how that goes. If I remember I'll take some photos.

Exactly this, don't be too scared to use wet and dry. But not 600 grit.  I would start around 1200 moving to super fine in small steps.  Then finish with facela compound and an electric mop (a proper one not a Mickey mouse fag lighter powered one)

I believe there are car waxes that have a UV filtering capability, and that ought to reduce fading.

I was told by one who claimed to know, that if you waxed your hull with silicone car wax, it wouldn't fade.  Tried it on my blue above the waterline L3k and it didn't fade, but it might not have anyway.

Can anyone conform or deny?

When i cleaned my Laser hull up prior to selling it I gave it an all over t-cut (to get rid of the brown 'tide mark' that the hulls seem to develop). Took me a couple of hours all told but the boat looked very shiny and the new owner was impressed when he looked round it.

I would avoid wet and dry, this is just too abrasive IMO unless you are trying to get rid of scratches.
