Default Re: Black turns bronzy black

sounds like your parts could be bleeding into your seal tank. Check your PH of both the sealer tank and dye tank. If the sealer tank PH is off it causes bleeding. A lot of dyes can run just fine at ambient temperature but I'd try to elevate the temp up to 140 F. As for getting the part sealed quick enough that isn't the problem parts can hang around for hours without being sealed.

12% is a little low in concentration.. ideal is 15-17% by weight.
