I haven't done any projects in a good number of years, but I have a few projects I did maybe 15 years ago and i probably used either:
Seal a Cell/Arm-R-Seal
Waterlox Orig
Wipe on poly
from what I can remember, those were my big finish choices back in the day.
Is there anything wrong with hitting these projects with a sander to remove the finish and then applying something like Odie's Oil over it to restore them? That seems to be the finish of the day, which is the only reason I mention it. I have not used it yet.
I have searched online for steps to try and determine the finish used and it seems rather complicated and don't know if I really need all those steps if I'm not doing fine furniture restoration.
On a side note, I have a cocobolo top/maple base table that I wanted to start on. I did start sanding and noticed that before I even started the finish was somewhat tacky. hoping the sanding removes this.
