Amazing company and product beats froth pak hands down!
I originally got the 650 froth pak by dupont. I wasnt very happy with it and was about 400 more a kit. Then i found this 605 closed cell quick set. They give you so much more instructions and the best part is the nozzel changes white as long as the foam is the correct temperature coming out. I watched SPRAY JONES on YOUTUBE he had tons of videos and if you watch them all well you would pretty much know all you should need to know except for experience part. It does say for professional use only and you better be well educated and skilled if you plan on doing this. The most important things are keep the cans very warm. I learned after the third kit to just keep a heater on them the whole time your spraying. That gave me consistently and was able to use both A and B jugs. It looses alot of heat when i took them out of my heated room that i set a heater at 90 deg f for 24hrs to bring the cans to 80 deg f. Also in the instructions it says you can spray at 1/4 or half trigger pull also. This helps you manage spraying so much better as the froth pack says to spray fullthrottle. I love how tip is both tips in one. I still have a learning curve on my spray technique. I used fan and jet sprays i feel i need more experience on that yet before i comment on that but i will say i was able to use 1 nozzel for the whole pak most of the time. The froth pak cloggeds up so much. I plan on making a video for this product to help people with a learning curve when i get my next kits as i need more to finish to follow my channel at backwoods homestead llc on Youtube. Happy spraying everyone be safe, RESEARCH, STAY VENTALATED AND WEAR YOUR PPE
