Cheaper and as good as 3m
3 pack Comes with a 3 reg nozzle and another 3 nozzle with 6” extension, but only one 24” flexible extension. Was concerned the 24” would clog between uses but haven’t had that happen sitting as long as week between uses. Flows well, I did 2 applications a week  apart on a Resto project wanted the first coat to set up and the second to fill any little pin holes there might be, really didn’t think it was necessary after seeing first coat but I’m anal. I usually hit areas with rust converter then an anti-rust coating like Eastwood’s hd anti-rust coating, then this stuff. It’s made in Sweden figure they must know how to deal with snow and rust...only “con” the 24” nozzle sprays mostly out in a 360 degree circle not much out the front. Which makes it difficult to get into tight corners like frt and rear of doors w/o flooding them with wax.  I’ll definitely buy more and cut nozzle off of next 24” ext. for pin point application w/o wasting product. I live in northeast so plenty of experience dealing with rust repair and prevention. Short of sandblasting, media blasting, and epoxy primering. I think this is the best approach to rust treatment for inside panels. Granted rust will always come back, but have plenty of past experience with rubberized undercoating ( drys out and cracks trapping moisture underneath increasing rust) fluid film ( need to reapply regularly) Never get more than maybe 2 yrs out of these type products, then you have to scrap an pressure wash and dry before re-applying. Jury’s still out on what to put on frames, underbody etc. Right now leaning towards spraying hd anti-rust coating in them, messy but doesn’t harden and crack or hold road film etc so the-coating is easier.
