i have quite a few plastic pieces to paint for my 94 Miata so I ordered some promotor and did a water float test with slivers of each piece. Initially only one of the eight slivers floated. However, after leaving the cup for a few hours I came back to find four of them floating now. Do I trust the initial results or results after sitting?
The really confusing part is that the rear bumper sample floats but the front bumper doesn’t. They’re both yellow/white (TPO?) factory pieces and the material looks the same.
Most of the other parts are cheaper, aftermarket parts that are very flexible and smooth, I’m assuming ABS and polyurethane.
