Ah, good news that I have not ruined it! So when you say oil it, I assume you mean with something like 100% virgin olive oil or neatsfoot oil? I only have the virgin olive oil.. and you mentioned putting a top coat, do I condition it before the top coat or after?
I have the eco flo clear matte finish and on my first attempt at this project on a seperate piece of leather I noticed that this finish is pretty good in that it repelled anything that I tried to put on after it such as water, oil, and more dye. But I messed that belt up and couldnt do anything else with it because I did put the finish on..
Edit: the conditioner I have is saddlesoap
