We just found an interesting article at Simon Eugster´s website a bit similar to what we have posted a few years ago. It´s about a short overview over the most common spray cans (at least in Europe) from various brands.
“I try to show the difference between the cans and the pros and cons. All available data sheets and the brand web sites are linked.”
The article comes more or less very correct, even a few little details have an individual view. It´s about dripping cans, clogged cans, internals, Healths and many more. If you are into this go and have a read at granjow.net
