Ohh I just realized you live in canada lol, ya you may need a head gun where colder temps are. I've also heard of people usein there oven to heat plastic up. You know how you open an oven an it kinda stays in a notch about 4-5 inches open, then then just set it on top so the heat cam out on it. Im not sure how well it'll work for bigger plastic though it'd be worth a try its free lol. Off the subject though im looking to get some trail tech light I like the bullet styl an there small I was hoping to get some feed back about them like/dislikes I can pick up a bar mount set for 130$
