hey guys... ive actually completed this project a long time ago...the oven wasnt a success so i went with dremmel...it wasnt pricey as i had expected only cost me $100 and 2 day-off to complete the project... there is NO fogging-up issue...when i used the dremel to separate the casing from the housing...I snapped it back with a super glue and a sealant... the good thing about it doing all of these was i could customize my tail to whatever i want including installing LEDs, all i do is de-glue the taillight and install some LEDs...
