Well, upon further experimentation, this is what Cranky thinks . . . if you are going to open and close your doors, trunk, or hood many many times, then go with the tried and true brass rod and tubing, but this works well if you are just going to prop up your hood or trunk open . . . to show off, say the interior . . ..
Also, I repeat, liquid cement will compromise the plastic . . . use gel type crazy glue.
