Dakotagrafx 7,297 Posted January 4, 2010 Oracal recommends installing on the outside - the vinyl is uv resistant but the adhesive is not. it is also harder to get it to look right on the inside when you can see the adhesive and the different areas it adheres Share this post Link to post Share on other sites

bamafan2277 50 Posted January 4, 2010 The few windows I have done have been on the outside. The one I did for my friends restaurant is holding up well. It is very cold here dropping to the single digits at night and his vinyl still looks good. He even cleans the window weekly. Share this post Link to post Share on other sites
mabscotthandyman 1,410 Posted January 4, 2010 Just use a good intermediate or high performance vinyl like orcal 651 minimum or my preference 751 they both hold up to carwashes and abuse on autos and trucks works great on windows. Dan Share this post Link to post Share on other sites
