Clean/Polish Hardback/hardtop

My hardback roof is looking a little grey. Does anyone have any tips on how to give it a nice black shine?

before anyone says, no I am not using fire to make it black.

Ive used this on my black trim,its like a black dye,a bit messy but does work , wear some rubber gloves its a bugger to wash off.

You could always give Mer Bumper and Vinyl gel a go it works wonders on most finishes, give it a coat followed by another a week after and it lasts for ages, oherwise turtle wax Ice in the clear liquid form is excellent as well.

Autoglyms rubber and vinyl treatment is tremendous stuff- makes all your placcy bits look like new and lasts for ages, Ive used it on dashboards, interior placcy trim, exterior placcy trim, tyres, engine bays. Always cleans and removes polish off the ectrior placcy trim if you have been a bit 'sloppy' when polishing. Highly reccomended
Will sort out your hardtop easy.

Thanks very much to you all. I will see which one is cheap and give it a go

Cheers.
