Heat and warping / melting / splitting paint etc


Hi. I am curious about heat and melting / warping. I need to know for both Grey04 and Grey Pro.
I have been doing 3d prints and putting them in my black car. They are pretty much all solid prints all the way through but some have thinnish parts. I’m gonna say 1/4 inch thick but some areas are proably like 1/8 inch wall or like the thickness of a mouse cable… and on the dash and painted in a matte black.

I have read statistics on this stuff but i’m just not sure exactly what it means. So I’m looking for any good information or thought on this.
