What’s your slip and dilution? I used 32oz zep bottle with 4 pumps of 7 generation soap with jj bottle dispenser and I have to heat it to tack into place for the top edge
U have to buy a mm measuring small cup...u have to measure EVERYTHING that goea into slip solution.. For example.. i use 1 oz to 1.5 oz tint Slime for window film installation...so divide that by 4 and u get about 7.5 to 10 mm per bottle.... If u use tirchvits either preference..or u using way too much soap... If u must mix a gallon...do so and dispense slip from there...slip thatbis not used after 2 days will break down and be ineffective.. Dirty ✌️
