Anyone know what plastic these video game controller pieces are made of? I cut a piece and it floated, so ADPRO was used. And, epoxy as a very light coat of sealer. Waited about 30 min the used activated base. Cleared with Speed clear. I had to sand a bit. Now it peels with my fingernail. I'm guessing I rushed the epoxy.
 
Some ABS has fairly low density and will float if there is even the tiniest bubble on the sample. I am imagining that to be ABS, if so it does not need adpro and it will also have poor solvent resistance, which means it needs thin initial coats and long dry times.

Probably needs a coarser scuff? Is a light coat of epoxy sealer too little?
 
The Google says abs doesn't need primer. I vaguely remember JimC saying that it doesn't too. He was referring to bug shields.
 
if you take lac thinner or acetone on a rag and wipe a small spot on the back, if the rag bites into the plastic then no sanding is really necessary. i would just leave it untouched, wipe with w&g remover, shoot a sealer coat of epoxy and then go right to base or ss.

if it is abs and it prob is then the adpro and rushing the whole process is what killed you here. you did right but once that base went on you needed to wait quite awhile before clear. those solvents need to come out of the adpro. that adpro and the abs soaks up the solvent and will reliquify offering no adhesion benefit. once the solvents all come out it will harden up like a rock then you clear it.
