Be careful what you buy.
Some of the tint is just that, a tinted plastic sheet, no heat reflection properties.
Cuts out the light, but has no effect on heat transfer and UV rejection.
Very true your better off buying the tint and having someone install it.
What brand of tints did you buy?Yes !
Try Plaza Alondra, next to the Gold Gym, on Av. Barceló, there is an Auto Adorno shop there ….had ours done there few years back ….girl there speaks English….
Brought our tint sheets from the US …paid only for the labor…and watched them install it …. to our satisfaction….still going strong after 5 years of Dominican sun…neighbor had to redo his tint twice in 5 years…so worth buying your own….
There’s quite a few Auto Adorno shops on Av. Barceló…take your pick.
