Seriously....I had the same deal....but on the sides of the seat. I'm a JEW so you the LARGE johnson thing won't fly....but I do have a fat ass.
Honestly, I used a black sharpie and unless you stuck your nose up close...you could not tell.
Other than that...bring it to a leather guy to have him/her re-surphase it. $$$$$
Call corbin...they may have a repair kit also.
I promise I won't stalk....I'll sign a waiver.
