Seat belt fabric Dye or Paint???

So I managed to wrestle up front belts retractors, the whole nine yards. I am also running rear belts the same way jason did. What do you guys recommend and brand if possible of red dye or red SEM paint. Same paint I would use to paint my dash pad. I had already soaked all belts in bleach water so they are all the same color. Someone on the forum has had to dye seat belt fabric at one time or another, Id hate to have all new webbing done, that can be expensive.
