Question About Tinting Double Pane Windows

[Undecided]

Is there a problem with tinting the outside pane of a double pane window? If not, does anyone know of a product that will stand-up to the weather? The other posts on this subject indicate that tinting the inside pane causes problems so we will not do that. Have not found any statement on tinting the outside. The outside panes to be tinted [very dark] are the slide side window panes which are not under a window awning. Thank you for any information.
