repaint leathers???

Hi lads, this will surprise a few, but my leathers are somewhat old and have a bunch of scruffs on them (well, I did come off at a few trackdays). Instead of buying new ones, as I really like mine and have grown nicely into them, i wanted to respray them. I thought there might be paint I could use, somewhat similar to stuff people use to do graffitti or so, but i have no clue obviously. If anyone has any smart suggestions, would love to hear them.
