Кто-нибудь менял сам пленочное покрытие (unibead)? Посоветуйте видео для замены!

Has anyone replaced their own beaded liner before ? Unibead? My husbands super handy and places keep flaking and we keep rescheduling water and we can’t keep doing it. Waters coming tomorrow place to replace liner flaked. He’s looking up YouTube stuff like he does everything and I’m just nervous. If you have can you recommend a good video to follow ?
