I'm wondering if there's a clear resin I can use to fill this hole in our wood kitchen benchtop. Gets grime stuck in there as it's close to the sink. Would also be tricky to sand and reseal so I'm hoping for something that I can leave set and forget. Thanks in advance!
Welcome to the Bunnings Workshop community @gemmaco. It's wonderful to have you join us, and many thanks for your question about filling a void in a benchtop.
You could use a clear casting resin to fill that hole, and it would be a good “set and forget” solution to stop grime from building up — especially since it’s near the sink. That said, I’d be a little cautious about how the resin interacts with whatever finish you currently have on the benchtop. Do you know if it’s coated with an oil or a hard polyurethane finish? If it’s oil, that’s generally fine — you just want to avoid applying the oil over the resin afterwards, as it can cause the resin to go dull.
Before applying the resin, clean out any loose material or grime from the void so it bonds properly. When pouring, you’ll want to slightly overfill the hole so the resin sits just proud of the surface. Once cured, you can carefully sand it flush. However, by sanding the resin to get it full with the benchtop, you'll scratch it up and turn it opaque. To return it to clear, you'll need to step up through sanding grits: 400, 600, 800,1200 and at least to 2400 grit.
If you do end up sanding the surrounding timber, make sure to reapply your original benchtop finish around the area to seal it properly.
Let me tag @Nailbag to see if he has any thoughts.
Please let me know if you have any questions.

No, it doesn't, @gemmaco, but if you are looking to recoat the area, test the finish on the resin to ensure it bonds adequately. If it just scratches off, it might be best to coat around the repaired area, rather than over it.
