Hi, my solid surface sink area is in quite a sad state after 8 years of use.. some of the silicon are getting thinner.. realised some parts are also leaking into the cabinet below.. any DIY ideas to clean up this mess.. i regreted not tiling the sink area when i did up my reno years ago. I was thinking of buying some water proof silicon and just go over the existing lining :.. need some tips to do this nicely
