Our finishing and Dye process is pretty dialed in and we are happy with it. I talked about it here with the dye tank I use
I just received the Blast yesterday and I am actually pretty pleased so far with it and its construction. So far on test runs it did pretty awesome.
Since that Dye tank thread… I added a Fry basket with handle so I can just pile parts up in that thing while every 5 minutes I give it a good shake to stir up the parts.
I also now have two five gallon buckets…one with holes drilled in it to drain. I will fill the solid bucket with water halfway to dump the parts after dying directly into it. I then dump that bucket into the draining bucket while hosing everything off…then back to the solid bucket with fresh water…back a fourth a few times to rinse the extra dye off.
Then I keep them sitting in fresh water, bring it to my drying table with a fan on it, and pull them out of the water and lay them out to dry.
I do all this to minimize the time the freshly dyed parts are touching the air before being completely rinsed off. It is also a lot faster doing the bulk of them in a water bucket then spraying each off by hand.
You will get no “blotches” and a uniform dye across each part doing it like this and it only takes a few minutes to rinse a whole chamber.
I used to pull them out of the dye tank onto a baking sheet, then run over to start rinsing each off…but then you have parts sitting there waiting to be rinsed while excess dye is drying. I would get a lot of dark excess spots etc… good news is, the dye is so deep that if this happens, after they are dry you can just blast them off again with glass media and they look perfect.
