Here is what I use:

*********s or M-F(Haven't used M-F but hear great things about it) on plastic
Spike-It on glitter
Spike-It or Do-It on colorant
Spike-It or Do-It on powders

On the colorant I've had several hard pack or bleed from Do-It. Hard pack so far has been pink and chartreuse. Might be more that have hard pack and will check tonight and report back. Colorants that have bled from Do-It are pink, orange and blue.
