I just kind of went for it, it wasn't too bad. I cooked em @ 250 for 10 mins start in the corners and gently pry. You gotta stick a flat head screw driver and get it under the lens to break the seal and work your way around. I ended up sticking each headlight in the oven 3 times, for the second and third I went about 8 mins. Then remove bezel, paint and reheat at same temp for 10 mins, then put the bezel/ lens( make sure to put the bezel in the lens before trying to put it back in the headlight housing) if you put bezel in first you won't be able to get the lens on. Then I clamped it for about 20 mins to let the glue set and then ran a bead of RTV/silicone sealant all the way around. If you take your time you'll be fine
