not-shiny bumper bolts?

[WebMonkey]

thanks, that's clear!

It's a separate piece, but it's crimped around the head of the carriage bolt, making it all one part.

They are just 1/2" carriage bolts. Although the non-graded ones have smooth heads, they aren't up to the task of bumper use. Grade 5 is easy enough to get at a hardware store (an actual hardware store, not a giant home improvement store) but the little hash marks will need filed off before painting.

that right there may just be the ticket. I was "assuming" that they were some special size or something. I will measure the length and see what the local hardware place has in grade 5 or 8. I checked that Grainger link, but they seem to have packs of 50, which is probably a bit much...

could you scuff them and use a primer?

Yes,I’ve done this on both the bolts and chrome bumpers

Hydrochloric acid or muriatic acid will make any chrome go bye bye.

I followed your instructions but now I feel strange. Were you supposed to use it all at first or over time? It had a bite, too
