Pay to have it professionally installed. It will look great and they will warranty their work that way if it peels,bubbles or F***s up for any reason that is due to the material failure.
Based on experience, removing and putting on tints is complicated. The complex glass curvature and heat-shrinking are far too difficult. So I suggest you leave the job to the professionals. For me, I always consult the expert on tints at TintBuyer for my window tinting needs, they provide quotations, tint law in every state and locate the best professional tint installer near my area.
