I want to color some of my ElaZtech plastics and know there are stains that will melt them. Can anyone tell me which ones won't?

Spike-it is the only one I've tried, and it didn't melt them.  It only had significant effect on lighter colors though.

Thank you

Spike it definitely works but don’t try jjs it will ruin it

Stains? I think you want to change colors with dye. Try food color dye it's easy to use.
