Anyone know at what temperature do headlight housings seperate from the lense in an oven? I am not doing this to my car but my brother is seperating the corner lenses on his e36 M3. (Since he can't find good smoked corners he is going to crack open some clear ones and spray the housing flat black).

Any help would be appreciated, thanks [:)]

He can cut em off with a dremel and then use silicon to put them back on. Also just a heads up for the painting portion: Blue painters tape will strip the chrome off.

Cut is such a bad word to use around cars but it works real well

Thanks guys, we will try out the dremel, is there a specific bit disk that will work the best?

put them in the oven @ 200 for bout 15 min......
glue should be well melted to pull apart if its anything like jdm headlights...
if not, must cut

why don't you just use some strong solvent or something and an exacto knife. might be a little loss impacting. never taken a headligth aprt myself though [confused]

for my headlights...previous car, i preheated the oven for 15 min. @ 250 degrees. threw the headlights in (in your case the corners) for 5-10 min and then pry'd it apart.

A heat gun will work well too. You just have to move around the edge of the lense in an even fashion. Don't hold the gun too close or too long or melting will occur.

Yeah we tried baking them at around 300F and they were still not coming off so we'll have to try cutting I guess. We were using his oem corners as test samples. The reason I posted it on here is because I don't belong to any BMW forums and I know some of you guys probably have some experience with this kind of thing, It's funny that we really can't find any smoked corner lenses that are dark enough to look good on the 3 series BMW, anyways thanks for all of your help.

I did it before @ 200F. I'll do the heat gun method this time around, never thought of that one.
