I just tried to do the headlight mod on the DEPO 2006+ Taillight you can get from Certifit.
I started at 175F for 5, 10, 15 mins.
Then 195F for 5, 10, 15 mins.
Then 205F for 5, 10, 15 mins.
Then 215F for 5, 10, 15 Mins.
Then 225F for 5, 10, 15 mins.
Then 230F for 5, 10, 15 mins.
Then 240 for 5, then about 7 mins in I hear a creaking sound, by the time I got it out, it had deformed. I atleast tried see if I could get it open, and end up breaking off a piece.
I gave about 5 mins inbetween each temp to cool down. Really sucks about 3 hours of work for nothing. I bought a replacement this afternoon because the one I did the mod on had a few scratches that were driving me crazy. So its not a total loss I am still using it for a demonstration for speech to show how nightshading reduces output. I really wanted to also show an alternative to nightshading that looked good. Oh well..
Gotta have a pic:

Yes that is water, it was a hot failure so I cooled it off with water so I could start cleaning up.
and to cheer things up a bit, here's a belt buckle I put together for my sister for her work's golf thing where every team had a theme. Her team was badass mother truckers, $9 belt from ross, $2 decal from the stockyards, and $5 sticker from pepboys =
