Well now the advice is getting kind of contradictive, so I will try asking specific questions:

1. What is "tack cloth"? I might've missed this step last time and maybe that's the problem.

2. How do I "wet sand"? With the oil itself?

3. What do I dilute the oil with? Turpentine?

4. If I need to sand off some oil to fix a spot, do I need to sand everything off? How to get it up to the same layer amount?

Thanks yaall
