Another little note that he forgot above
when applying it, the asphalt paper applys a lot better and melds to your trunk crevises, if you use heat. A heat gun works very well, and honesly, this stuff does not start on fire so if you have nothing else a hand torch works just fine , i did a whole car with a hand torch. in the summer its not such a burden, lay the roll in the sun, and then just take it right off the roll. when its real cold, like it is here (ne ohio..snowbelt) heat is a necessity, because the tar wont stick almost at all in cold weather, but a lil heat goes a long way.
get a few rollers if your doing a big car, because it does build up after awhile...depending on what heat you use..
as he said, if you have bubbles , cut them and then rollem out.
It will not come off, you can scrape it off, and heat it, but its still gonna leave a nice tar residue (just like that one in your lungs) so use your head when applying it
