I thought that the reason for my failure in my first attempt was the absence of sufficient precaution against dust, also re purchasing the second product second time, this time I took a max precautions, gloves latex, thorough cleaning of the laying support table, etc ... and much macroparticles left by ... the black cleaning cloth that rubs off! .. and whenever possible to remove the dust of the film in contact with the ps destination bin; Then you tell me, I'm really not good, except that I must report that my first installation of the Sony film starter kit was impeccable at once without special precautions, and if one of my children, did not damaged, I would never have had to engage in such pain! = product to avoid!
