Was considering getting some PBT dye sub keycaps then dying them (with iDye Poly as per past recs here). Thing is, would the heat necessary for the dying affect the dye sub legends?
According to Wikipedia for polyester textiles at least the temp at which the dye sub process is transformed is 180-210°C which is far above the less-than boiling temp needed for the DIY dye however I didn't notice any user experiences so thought I'd ask.
Anyone experience issues with doing this?
