Does anyone know which grit to use on an engineered marble sink to remove old mineral stains?

The higher the better. I have used 3000 grit on porcelain and it works great at removing mineral deposits. Do it wet.

Which one works best for resin? and the lower the numbers the more rough paper is? or how does that work. thank you

Yes, the lower the number the more aggressive the sanding. All of these would work fine for resin, it gives you low enough grit to take off material all the way up to 5000 grit for a polished look.

Has anyone used this for polymer clay? if so was there any issues?

I have never used it on this material but see no reason why it wouldn't work. This is some very good and very fine sand paper that has worked on very things that I needed it to do so if you need a good sand paper that will do a good job without leaving any sanding marks this is it.

Can I use this for resin pieces?

I think given the fine paper included. I was smoothing out scratches on stainless steel at 1200 grit I’d start with 2000 for softer materials
