Just a quick review of Vaper Spot Spray Non Aerosol Sprayer, green #19424 blue #19424 I did end up changing the Schrader valve in the green one it was messed up.
As for your defective aerosol cans, I would buy the same exact cans to keep and return the defective ones the next day with the good can receipt. Why should you get stuck with them? Just sayin 🤷
I have never used fluid film before, So I'm unsure of the consistency of it I don't want to give you false info. I have only used them for WD40 and CRC Brakleen so far.
I do not recommend this brand. I went through several of them on Amazon. Customer service would not send me any parts under warranty for them. They just told me to return It to Amazon and to order a new one. They all leaked horribly.
I was going through the Amazon reviews before I bought them, There were a few people writing there's were leaking and other problems. These haven't started yet (fingers crossed) We used Zep ones at work they were good but pricey.
