Nice technique. Looks like there would be a very high risk of getting contanimation on the adhesive. I see you remove the backing @ 4:20 and then reapply it at 4:25 then roll it up. Now @ 5:20 inside the car you unroll it and the backing has already been removed. Im confused as to when it was removed.
De las mejores formas de trabajar , y no se diga de las herramientas especializadas que tienes, a mi me encantan esos pulverizadores de doble acción, te ahorran demasiado tiempo. Saludos desde matehuala S.L.P México.
