So ColorFill's in the lead. I've not used anything except bolts, so curious to see what others are doing.
Ahh I'd do that if I had laminate worktops to do which didn't have a kitchen sink incorporated into the design of the kitchen. Colourfill or silicon every time for me ( I find the colourfill goes off a bit too fast if I'm on my own though).
Just to point out I do apply clear varnish to seal round sink cut-outs It seems to do the job. I saw a video on Youtube a while back of a guy who had developed his own patented sealing goo for cut chipboard. He was selling it online and said it had "secret" ingredients.
