What I did:
- Zinc Chromate the frame where the epoxy was
- Then a zinc rich powdercoat primer was used
- Topcoated with powdercoat of finish quality
Since the trailing arms were sooooo bad I got new
ones, hot dipped zinc and powdercoat for color
match. The zinc does get everywhere and needs to
be removed where bolts are used (such as the
trailing arm holes).
This was done many years ago (25'ish) and before
DMC support via the internet was as good as today.
Not exactly what you asked, but FYI...
Here I come with another very technical
question. What is the preferred method
of coating a frame? Here are the choices
I have and I don’t know what to do.
I would like to have the frame zinc
coated but then I was asked how I want
it done. It can be dipped in a molten
zinc giving a thick and strong layer.
Another way is electro plating the zinc
onto the frame.
Hot dip – thick layer, good protection,
gets into all little nooks and crannies.
Electro plating – Thin layer doesn’t
affect bolt threads, adds very little
Hot dip – thick layer, increases the
weight of frame, a lot will remain in
all enclosed spaces
Electro plating – doesn’t last as long,
doesn’t coat inside enclosed spaces
Zinc coating is fairly inexpensive and
I’d like to do it. I can also have the
frame powder coated to increase the
protection even further. What do you
guys think? Should I go with the dip
process or electro plating? I was
thinking about electro plating + powder
I’d appreciate any input. Thanks.
