Subject: Re: what kind of paint for cylinders ...

Well I would not let them dip galvanize them in zinc, otherwise, for
steel bottles , the 160°C for powdercoating does  not come near any
temperature used in heattreating steel. Tanks are made of a steel alloy
keeping its tensile strength under heat anyway ( at least here in
Germany )
The normal baking temp for cars/ paintjobs is below 80°C I believe, so
no reason to worry about.
Totally different to aluminium. But in Europe, steel rules ocean diving
