Message: I play disc golf and would like to do some custom dye jobs on some of mt disc. They are plastic and can't find any direction on this. How wuold you do multi colors? Any help would be great.

The type of plastic used to make the disc is very important, in selecting the dye. My understanding is that most discs are made of nylon. Nylon can be dyed by immersion in a hot bath of acid dye; for best results, the dyebath (hot water plus acid dye plus vinegar) should as hot as you can get it without melting the nylon. (This type of dye is not nearly as scary as it sounds, as the name "acid" merely refers to a small amount of vinegar used to help the dye process.)

To dye multiple colors, you hold the disc only partly submerged in a hot dyebath, or else you mask out part of the disc so that it is unaffected by the first dyebath. Then you repeat the process in a different color dyebath.

Although all-purpose dyes don't perform particularly well on cotton, the fact that one of their ingredients is acid dye means that they work nicely on most nylon, so you can just buy the little packets of all-purpose dye sold in many grocery stores and pharmacies. For larger quantities, you will find the selection of dyes at ProChem (see my Sources for Supplies page for contact information and other sources) to be wider and much more economical per disc.

There's a page of instructions for dyeing nylon discs with a paste of all-purpose dye at www.discgolfreview.com/.
