...and remember, wrapping is about doing it the best way possible, sometimes you will find you need to join the wrap so really, there is nothing wrong with wrapping your mirror in 2 halves as long as you can hide the join somewhere, let one piece overlap by a couple of mill. When im wrapping, sometimes id rather use a join knowing it wont fail somewhere done the line rather than taking a chance and having the customer return unhappy...which, so far has never happened i might add!! Just remember, post heat post heat post heat...if you dont do this, it WILL fail around tight curves and areas where you have stretched the vinyl. Sorry to say that there are a lot of wrappers out there that cut corners, dont post heat enough and also cut on the car...hence why the trade has a bad name, especially on forums.
