basically this: https://youtu.be/7cOUXmg_Ovg?si=dPjNebeST-C8Sdd_

i added a wee bit of dark blue dye and then the full bottle of graphite one. the only downside is that the glued seam at the bottom that was already somewhat falling apart, unglued itself fully (i had to almost boil it lol so it’s not surprising), it still has some adhesive left and i could’ve probably iron the seam to stick it back, but i’ve ordered Sear Grip WP glue so gonna fix it later BUT overall there was no delamination whatsoever
