Adding Refrigerant without a Low Pressure fitting

[Mark R]

I'd be leery of the burst pressure of the cans... and the shrapnel if
there's a mistake.  Anyone know the burst pressure of the cans?

I'm wondering if its possible to add refrigerant via the high pressure
fitting, with the car turned off.  I figured that the aerosol can is
probably pressurized enough to overcome the 60psi and get at least some
refrigerant in, but it surely won't overcome the 150psi present when the a/c
is on.  I appreciate that I'll get a lot smaller fraction of the can into
the car via the high pressure valve at 60psi than via the low pressure at
30-50.  The only impact of this is that I'll require more cans.  Anyone see
a flaw with this?
