    Well I was using it on Classic's Prowl's door's to remove the paint from the doors and the plastic cracked in three places, I did not leave it on or let it set in the Alcohol I used a q-tip to clean the paint off So i would advise not to use 91% Isopropyl Alcohol on any of the Universe transparent plastic.

    Yeah, it's pretty amazing how quickly even a little bit of alcohol can affect the plastic. I was shocked when it happened to my Classics Bumblebee... just a splash of the alcohol, and the structure of the plastic just crumbles.

    A shame that it's more of the same on Universe Prowl. You'd think if they had to use lousy plastic, they could have at least done a better paint app. :(

    I know that NP has had some problems too with some Animated parts doing the same.

    As a rule of thumb, I usually soak my part in 70% first, if that dont do the trick on removing the paint, I'll then move onto the heavy stuff (91%)....I do this just to be safe.

    I had to crazy glue the door parts back together, and We should have some sort of compiled list of Isop and what percent to use on what plastic.

    Yep, Ani Cy Prime's Lightpiping is toast cuz of 99% Iso,
    also had the same problem with Excellion's door panels.
    Only 2 molds I've ever had a problem with the clear plastic.

    I am wondering if this isn't a chemical reaction with the plastic or the fact that it is cooling down too quick causing an expansion/compression stress fracture.

    I have seen something similar happen when everclear was poured into one of those two wall insulated cups. The inner cup pretty much shattered from the heat being drawn out of the cup from the alcohol.

    I was lucky to find the 91% but I never seen the 70% just the 51%

    I always assumed it was a chemical reaction. Like clear plastic couldn't handle the alcohol.
