Hi all,
Big fan of spi products.
My experience with metal prep/phos acid involves parts that don't matter and rattle can. Had no issues.
I'm aware of the neutralizing steps for phos acid before epoxy, to include various threads and of 13 of the tech manual.
My question though is, regarding the orange tinge after washing. I watched a video on the bonderite product (phos acid and zinc phosphate 2 stage coating). Guy mentioned neutralizing it as specified but he stated the orange tinge after washing, is a zinc coating and no issue.
For those more experienced, is this actually surface rust or what? If it is caused by minerals in water could a guy use a tub of deionized water, or something to reduce that?
