Were the door striker bolt tips painted during factory paint?

[weider1717]

Just curious worked on my stiker bolts lately and mine I noticed the round tips on mine along with the 3 washers are covered in blue paint.

My truck has never been hit but it was repainted by GM in 1991 under paint clear coat recall.

Needs paint again and curious if thats the way it should be from the factory or not kinda taking note how to tell the paint guy I want items such as this done…

truck is an 87

thanks for any insight
