I have an Ontario Rat-7 that I need to do some modifications to.
Supposedly it has a zinc phosphate coating on it.
Once I have finished my mods, can those areas be re-coated somehow?
If so, how?
Is it similar to cold bluing?
I just want to put a little something on those ground areas to protect the 1095 a little, I don’t care about looks.
I have thought about just using some Birchwood Casey cold blue to touch-up those spots or a mustard finish (Goddard style)…

Wanted to get your thoughts.

Thanks,
Brome
 
Zinc phosphate [and manganese phosphate] are referred to as 'Parkerizing' used in military weapons for years .They hold oils well so protect steel from rusting. You could have the whole blade redone [without handles] or you could touch up with cold blue .I don't know what a 'mustard finish' would do to it but you could try a spot.
 
I'm not sure if this helps but I was at home depot yesterday and they had a phosphate metal etch for sale in the paint dept..It claims to be a rust remover and creates a patina that stops flash rusting on metal. I'm not sure what type of patina will result from it's use..

I have used a like product years ago and it does turn black. I've got some old Naval Jelly that I believe is the same thing. Been meaning to give it a try but it keeps getting over looked.
 
Naval Jelly is phosphoric acid in a gel.Coke Cola is also phosphoric acid !
