all this is good advice, blisters in paint can occur from dirty surfaces, primer that isn't cured well enough. prep work is 90 0/0 of a good paint job, don't rush to get the job done, ask your local paint store for advice, it's easier to do the job right the first time than to do it over again. the base coat clear coat is a breeze to apply, follow the directions on the can, these guys (engineers) developed the product, they know the best ways to apply.
