Thread: about to galvanise my 110 firewall - anyone else done it?

If warping / twisting worries you, weld a couple of stiffeners to it.

38mm x 6mm flat bar on edge would be heaps i would think

stitch welds only 5mm long in several places on each brace will be easy to remove and will be easy to rustproof with cold gal or whatever takes your fancy after removal.

galvanising usually normalises steel so it can move anywhichway but can usually be put back where it was with some patience and a portapower and chain block or two.

welding the footwells in will create some stresses to start with i would thing so it could be a good thing alround to galvanise it.. dam sure i would do mine if i had the bucks...

Hey Mark,

I have no experience in this but have every intention of hot dipping my Series 2a bulkhead when I have done the small repair welds to it. I have heard of others success in doing it with only a very slight warp across the panel where the vents sit ... it's thinner along there. One solution is to get the guys to leave your Bulkhead to the very end of the process when it's not as hot and extreme ... I believe they can actually control the process to a certain degree and still achieve the same results with less chance of warping.
I'd have a good chat to the operator before you do the job and explain your needs. Where and how much did it cost you to get your Series B'hd done last time?

Cheers, Simon.

Actualy its not that expensive. Around $60 to get a firewall dipped plus about $100 for the sandblasting. I wouldnt want to be paying someone for the labor to strip and refit it however..........

I've got not the foggiest idea, but I wanna know, I wanna know.

Keep us posted and piccied.



Cheers
Simon

I've already asked them about the cooler dip - apparently this is a myth as if it gets too cold the bath freezes - and they dont want that. The place I use (at Narangba on the north side of Brisbane) works 24 hours per day.
The current rate is $1.20 per kilo of galvanised weight. A firewall only weighs about 25-30 kg. Galvanising might add about 3kg to it.
I had some slight rippling in the 2A firewall which was hidden by the olive drab lusterless paint and a bit of difficulty refitting the windscreen frame. The captive nut plates for the door hinges in the 2A are a bit of a pain as they sieze up and make refitting the doors a bit of a challenge as well.

G'day Mark,

I don't know much about galvanizing firewall but was warned against it as risk of warping.
I have a 110 firewall that needs repairing and treating. Have a look at POR15 paints. Very expensive as far as paint goes but a lot of car restorers are using it. There is a company in NSW that imports it. This is what I will be using.
www.por15.com.au
You also mention that they will be putting in new footwells. Have you been able to source these as only ones I can find are from Series firewalls and the footwell are different.
Let us know what you have done.

I believe our English cousins have had a long association with POR15 and there are some serious health risks associated with using the stuff so it might do for any potential users to make sure of the do's and don't of that stuff to guard against injury in the long term.

I was told by the bloke in Brookvale, NSW not to gal the firewall - he is also a LR nut.

He recommended blasting and then "organic" galvinised spray.
