Our 2004 Troll roof has gone a bit hazed in its previous life. I'd like to restore the shine, but am a bit hazy myself when it comes to cutting and polishing fibreglass.
I have located this product which seems to fulfil the requirements, but wonder if anyone else has experience of this or wise comments please?

You mentioned about being uncovered, just wondered (slightly off topic) your thoughts on using a cover

Sorry, Randa, could you be more specific about the type of products? I am not an expert in the field. I searched on websites and found many and for a thousand uses. thank you

Randa - Shampoo and conditioner or just shampoo

I am reminded that, following a spate of celebrity endorsed shampoos a few years ago, Bob Geldorf jumped on the bandwagon. His was called “Go and Wash”!

Back on topic for a moment. If you have serious stains on the lifting roof you could try Grunt gel coat cleaner (available from the ubiquitous next day delivery lot for around twenty quid) Used by many boatyards to get rid of serious stains. You paint in on with a brush and then wash it off after 20 minutes. It is very very effective.. half a litre will do one roof.

I've recently done my 540GT - purchased some "Gel coat restorer" from a seller calling themselves "cleaning-clinic" on eBay. A small 120ml bottle arrived and I thought OK I'll make a start on the main part of the roof and see how much it will do and if it's any good I'll buy a couple more bottles (they are only £5.99 each) anyway the bottle did the main roof and the poptop roof with a little left over! - It's truly amazing stuff, has got rid of the chalky matt finish and now the whole roof is extremely clean & shiny - It was fairly hard work teetering on top of a ladder for several hours but end result well worth it.
