Review: Seems to be working well, for now… - Mine was a VERY small leak, so hopefully, this will last. Instructions were terrible though. Apparently, you’re supposed to let the unit’s suction “pull” the sealant into the lines. I’ve never done this before, so that was anything but clear. But, I digress…
Review: Excelente producto, económico y resuelve - Excelente producto, tenía una fuga de gas en mi unidad de aire acondicionado, llenaba el gas y a la semana ya quedaba si gas, aplicamos este producto con una carga de gas completa y ya llevamos mas de 3 meses y la fuga está controlada, me salvo de cambiar toda la tubería o hasta de cambiar la unidad porque al parecer la fuga estaba en el compresor y era muy complicado de reparar y en un equipo de 10 años casi ya no valia la pena, así que este producto le dió tiempo extra a la unidad.
