being an automotive novice and dimly remembering high school japanese class combine in fun ways when owning a jdm vehicle
btw if any japanese speakers can work out what this says please lmk. was written on the interior left wheel well. best i've got is "wakuuzu [EDIT: waKOOzu] riiku sutoopu"? something leak stop?
