Ive brought a new bulkhead, its in the bare black primer, what do I paint it
with to prevent it rusting like the old one?

Do I treat areas on show and the underside differently?

Regards

Have it bead blasted and zinc sprayed

AWEM

Get it galvanized

Seconded - it's harder to get a decent paint finish onto it with galv
but if you can find a local firm who have a bit of skill galvanising
(and that bit is important!) then there's little will match galv,
filling with warm waxoyl and a couple of coats of paint.

Zinc spraying is a probably less risky process (never had it done on
anything) but not so effective in protecting the inside of the
bulkhead, I take it Andrew is talking about hot spray as opposed to
Galavafroid or similar.

From what I gather, hot-dip galv is apt to give you a distorted bulkhead.
Presumably the electroplating method is OK though.

Thats interesting, didnt know there was an electroplating method.

How good is galvafroid?

's good paint. not the same as galvanising.

techincally, galvanising is in fact electrical I believe - the word has the
same root as glavanometer, for example.

it involves a tank of some sort of solution with lots of zinc in it and
presumably lots of volts.

That's electroplating - IIRC zinc galvanising is simply dipping the part
into molten zinc and withdrawing it letting a layer of zinc harden on the
surface - the "Galv" in this context refers to the Galvanic effect where
you have two metals in contact with each other in an electrolyte (water
mostly) and they generate current - the way this works for galvanised steel
is that in this setup the zinc is a more reactive metal than the steel and
as such it sacrifices itself through electron transfer when there's an
electrolyte present - the steel doesn't suffer because the zinc sacrifices
itself.

If you have a firm who don't know what they're doing having only done
things like posts of thick steel and the like then chances are you're
going to end up with a rather hard to fit bulkhead, yes. Not the case
with the one I had done though, and I've seen plenty others.

That's different again! From the talk of bead blasting I assumed
Andrew meant hot zinc spraying, rather similar to hot dip galvanising
than electroplating.

For the chap asking about Galavafroid, I did a series II rear cappings
with that and it's petrol cap and it wore through/off in places in less
than two years. Looks very dull as well, doesn't age that nicely
compared to real galv, but then that vehicle does live on the North
East coast and there is a lot of salt on the road compared to other
parts of the UK.

Absolutely. Had my trailer done 10 years ago with a Metco zinc spray
gun and it's stood up to alsorts of misuse very well.
