We got Llumar ceramic window tint for our van and we're gonna attempt a self-install... Getting it professionally done is just so pricey and we're confident we can do it, but I'm wondering if we'll need a heat gun for any of the windows to install the tint. The windows really aren't very curved at all which makes me think we shouldn't need one, but I'm wondering if we will based on others' experiences tinting their Transit windows themselves. Did you have problems without a heat gun? Any suggestions in general? TIA :) #lifestyle
