Bring the door-glass details into the plan
Some coupes have frameless or indexing door glass. Tell the shop how your windows behave when a door opens and bring the vehicle for evaluation. The preparation and aftercare discussion should reflect the actual window mechanism.
Compare the look in more than one light
A bright white coupe can make tint appear different from the same film on a darker vehicle. Ask to review physical samples and discuss existing glass. Choose the quoted film and shade by product and window position, rather than by the appearance of a promotional image.
Make room for the care instructions
Ask how to use the windows during the product’s curing period and what cleaning method is recommended. Obtain the selected film’s written warranty. The shop’s five-year or lifetime coverage depends on the film and its terms, not simply the vehicle style.
