I've been lucky with stripping parts and shells, never had an issue. But, I have never striped a shell that has had an extensive amount of filler. The have left completed builds soak in DOT 3 brake fluid of over a year with no notiable damage to the plastic, even the windows and lenses were ok. The only effected parts have been the tire's (those off road dessert dogs) they turned hard.
I have also left parts in Easy-Off for over a year with out any issue, windshield too.
I have a 1940's panel van chopped project that went sideways from years back, it's full of spot putty, I am going to toss it in brake fluid to see what happened.
