hey mate, i went the other bunnings option the white knight rust converter, i already had a litre of it from when i treated rust on my gq, seems to work well, its phosphoric acid based and turns surface rust kinda blackish looking, but its a couple of years old so i duno if it has a use buy date or anything so i thought id just see how it goes, ill need more anyway to spray the inside of the rails so maybe ill have a crack at the bondall,
yeah the white knight stays tacky for a while too, i might be putting it on too thick tho i duno, and nah its horrible over here, feels like its just been cold and rainin for months.
