I did this and still managed to fuck the surface up with a boiler that died and leaked a load of brown shite all over the surface - ruining it and about 700 quid of cook books that were stacked beneath it. Had it looking good for about 3 months, then had to get a new boiler and stomach the stain for the sale pictures - we drilled in a bit to see if it could be sanded back but it was so corrosive it just wasn't worth the mess.
I'm glad I've scratched the wooden worktop itch then sold the house less than a year after installation.
