I've tinted flat windows, no problem, I can do it without a bubble.<br /><br />...I've got a '95 Galant, and the back window has a pretty good curve to it.<br />Called 2 Tint Shops, $110 just for that one window!<br /><br />So, I will do it myself, as I can do the entire car for $20 in material.<br /><br />What are the tips to doing a curved window?<br /><br />2 pieces? Heat Gun?
