I will say this is far worse and more likely to happen on fresh metal. Once blasted there is a much better 'key' for the coating to stick to and any lifting of the coating is more localised.
All in all though fella...........the idea is pure **** for most applications where damage is likely to occur to the coating. Your best bet would be to have the entire tank etch primed and painted. It may be worth your time and effort having the side closest to the road applied with that rubberised stone chip guard stuff. That is overpaintable too so it can look tidy as well.
Just my experience and opinion but one to think about mate.
