Grave Digger Tires
 

Hi y'all. I'm a new member from South Carolina. I was hoping someone might have some advice for me.
I purchased an Axial Grave Digger. I noticed after a couple of runs that the lettering on the tires was coming off. I never hit anything or brushed up against anything.
I cleaned it all off and redid the lettering with the same size adhesive lettering from Hobby Lobby. What I would like to know is if there is anything I can do to make it permanent. Is there anything I can coat it with that will sort of protect it?
