That's a good question, I didn't keep track...... I'm sure there's a full roll per door, so there's two. Guessing another 4 rolls, so maybe 6 or seven total??? I also put this same stuff (peel & seal) on the ceiling prior to installing new headliner. The underhood kit from LMC makes a noticeable difference. The factory stuff on both sides of the firewall + the coverings on each of the fender liners is good stuff and I'd never suggest removing it. New weather stripping around door openings is another improvement.
