The biggest problem I run into is a lot of the dye coming off when I apply the finish, in my case has been Eco-flo satin sheen. It has been an especially big issue when I have more than one color because they bleed into each other. I've also had the issue of the color lightening up a lot and becoming blotchy after applying the finish when it was a nice solid color before the finish. Any suggestions on how to stop or minimize this effect would be very welcome.
