ive used both a heat gun and the oven several times and i prefer the oven. you only need to turn it up to 200. i did some taillights once with a heat gun. ended up breaking the lens on the aftermarket ones in several spots. oem taillight was ok tho
no offense dude, but making your turn signals blue is a terrible idea. i doubt you will be able to go a whole month with out getting a ticket.
i understand what you mean when you say a bunch of stuff is illegal on your car. but the signals are kind of a step over the line.. tints arent a big deal and blackhoused headlamps and tails are only bad if you really cant see through them
i really dont reccomend this. but if you must, i prefer the oven, just dont forget your mits
