That is old school way Gav, mine is done like that and most of the bog that was done 20 years ago has fallen off with rust behind it, can show photos if needed, supposedly the heat reaction causes the bare steel to sweat, that is why new school do it on top or etch primer.
In fairness I didn't see a teacher doing it this way, it was another student in the paint section doing it.
I epoxy then filler then re epoxy then prime. I also dont touch any bare metal without gloves.
Yes I tried to avoid any bare hands touching the metal after blasting.

always hard to convert the foagies, most never re-train anyhow, and that includes 'trainers' themselves.
If we lived by the old philosophies, F1 would still be steel caged cars, our forum would consist of pen & paper and maybe we would never have discovered light & lasers.
boy has the world come a long way in the last 60 odd years....too bad the motor car has not!
I would only recommend treatment of raw steel, either phosphate or chromate resultant products.
Of which the super etch is one of a handfull of the best there is as far as a 1k ep etch suitable for almost any further surfacing/finishing.

Tried to buy Wattyl super etch primer at Bunnings some time back, was told that they don't sell it anymore. Also local paint shop
informed me that "White knight " is a Wattyl product .
