well, for b13 stock head lights what i did was;
-cleaned them with windex,
-preheat oven to 275.
[put a cookie pan on the very bottom rack , so the heat will dissipate]
-when it beeped threw them in for exactly 2mins or no longer than 2.20
-took it out right away. and pryed on it with a flat head its kinda hard to do but it'll work out...
[it'll be relly hot so use a thick towel to hold it down while pry'in on it]
you can put them back in for 2 mins and push them back to gether or just use liquid nails.
