Aghhh! .. I should not have left leaked the oven cleaning liquid on top of my new granite top (I think its' what it's called). Now big area of the surface is damaged like this http://prnt.sc/f5y42w and I have tried http://www.wickes.co.uk/Ltp-Mpg-Sealer-for-Polished-Surfaces-1L/p/119832 which doesn't even help tiny bit restoring the glossy top layer. By the look of undamaged area and comparing with damaged area, some kind of clear coat was applied on stone surface before which has been eroded away by oven cleaning liquid. So I was wondering where I could buy that top protective coating again to repair damaged area. Any advice and tips will be massively appreciated.
