Stripe's pretty easy - I did it by myself without assistance, first time I've applied one or even seen one applied. Follow instructions, use plenty of solution, the "squeegee" provided works well, but wrap a piece of cloth around it to help minimize any marring of the decal. Bubbles happen - don't get aggressive if you can't work them to the edge, better to prick with pin/exacto and work out with squeegee/fingers. Smaller (tiny) bubbles will evaporate within a week or so. Remember, I've done one - there are those here that have better advise and tips than I. Mopar Muscle has an article on line - bumblebee on a Charger, search their site. Now the vinyl top - that was another story !
