Hello,

For protection of the pins before spraying , use the thing you can find at
McDonald for drinking Coke (you see I know about everything about the
American Way ;>))

cut to pieces, it will also protect the thread of the agraffes holes before
spraying.

You could also on some plates, if enough space remain between the agrafes,
make a little "hat" for them with some thermo-retractable pipes as used for
electronic, many sizes exists, some make perfect caps for many tools,
voicing tools, blades, and so on. A bit of warmness on this pipe and it
react by becoming much more smaller, then stiffen a bit.

If you don't have a compressor you may use spray cans, and a lot of them if
you want enough paint. I spray with air and use polyurethane lacquer with
bronze powder in it. This is more resistive to scratches.

For the  screws holes in the frame, best is to ream their inside before
installing the screws, so the lacquer remain clean at the edges , if you see
what I mean.

Not so much words in my English to explain more clearly.

Hope it helps.

  I clean the screws with a wire wheel on a grinder. I put them in a box
with chicken wire. (the very small squares, which are about 1/2" square),. I
spray them with the same gold paint as the plate. Unless they are nickel
plated to begin with. You should polish those up, and spray them with a
clear coat of lacquer.

  I leave the hitch pins in, and spay them. That is not a problem. You can
spray the agraffes, too, but for a super look, take them out and polish
then, since they are brass. Keep should them in order when you take them
out, and put them back in the same hole.

              Gerald-Wim,

              Someone mentioned putting a spent firearm shell casing over
each agraffes before spraying.. I haven't tried this yet and can't remember
the caliber required. You could bring one to a gun shop or mic. the O.D.
