need help with testors acrylics remaing sticky

Posted in Custom Workstation

hi
my first post here
(I tried to post once, it never seem to have come up, I apologize if I post twice)
I'm big time into batman customs
I'll get around to submitting them all real soon

I used to use the $1 cheap arylics, some were great...some were not
now I use the testors acrylics (expensive) but they apply smooth and are much more durable

I've been having issues with testors arylics remaining sticky after drying, or almost like never drying on certain types of materials
like soft rubber, bendable rubber plastic, the soft bendy materials, not all but most, like certain type of figure's hair, cape, skirt, cloak, sports jacket
also having the problem on hardened sculpy
even a week after being painted its sticky to the touch, sticky enough that touching it takes the paint off, and if it falls on the floor, its collectors dust/hair big time
you touch it with your finger and you have paint on you, and you can see where it is coming off

I used a glossy black on hardened sculpy with that problem, I used a yellow, didn't seem to have the problem
the only solution I've found is if I find it remains sticky, to use paint thinner, remove it, paint it with $1 acryls, then testors on top of that so it matches the rest of the figure
this is not a good solution
I use testors dull coate to seal most of my customs I also have matte sealent
both work great, but neither fix the sticky issue

any suggestions plz
