Hi!  I'm new to the boards.  I'm not a leather worker; at this point I would probably be best described as a torturer of leather *LOL*  I made a really stupid mistake, I'm hoping to find a way to fix it! 
I bought a beautiful western saddle.  The tooling is incredible.  It appeared to have been a display saddle that had never been ridden in.  The good news is I got it for a very good price.  The bad news is I ruined it.  My goofball horse laid down in a bog with me, getting black tar mud on the saddle.  I had to really soak that mud to get it off, which darkened the leather.  I waited a couple of weeks to get it good and dry then tried oiling it to even the color.  Now I have an ugly blotchy saddle.  It appears maybe a sealer such as Saddle Lac may have been applied to it? 
I looked online and found out about deglazer, but the product description says it removes dye also?  I don't want to remove the dye, just the Saddle lac so I can oil the saddle again and try to even-up the blotchyness.  Is there any hope? 
Thanks in advance!
