S2 chassis currently away being blasted and I'm considering paint / coating options. Anyone on here had experience using Galvafroid ?

I haven't used it or previously heard of it, but the requirements and limitations listed at this site seem to be rather onerous compared with other products, particularly the requirement to overpaint with a second specialist coating when exposure to corrosive conditions (eg salty roads) is likely :

there are a couple of good threads on the chimp page about painting chassis. Check out Classic Chim and ChimpOnGas.

Thanks Bob, interesting spec document

My Dad painted our new Landie 2a rear cross member with Galvafroid and it held up fine for ten years (1970's), no rust when we sold the beast onwards. There are better things to use these days though.

I had mine painted by Global Coatings in Knutsford, Cheshire who specialise in blasting and painting equipment for mining, notably stuff that sits on North Sea oil rigs for 20 years.

Not expensive at all surprisingly.

Thanks for that, good looking job on the chassis
Unfortunately I have little faith in powder coating given the state of the chassis once I had her stripped but I suppose the original job was done using techniques that are now 30 years old, the chassis hasn't been re coated for 30 years and I'm guessing techniques and materials have improved over the same period.
Just can't get the image out of my head that once the PC is compromised, moisture works it's way under and blows huge areas of coating, that's all.

Whilst I'm on, don't suppose you know the purpose of the small phillips head screw that screws into the top of the upper wishbone is do you ?

My S1 doesn’t have any Phillips screw on the upper wishbone. Take a photo to show what you are referring to, this would help.

That is not standard and I can't think of any good reason for doing it.

Both sides?

Can think of no reason for that other than perhaps hiding a hole where it has completely rusted through from the MOT man?

Maybe it was put there for a reason, but I doubt it was for a good reason. By now these cars are all old enough that they could have passed through the hands of bodgers along the way.

You can't compare the genuine powder coating, which was a single polyester layer, and a great current 3-layer powder coating. The first layer is a zinc-rich one, to give a galvanic protection, the second layer is an epoxy one, to give the strength, and the last one is polyester to give the U-V resistance, to keep the colour.

I have already used this solution for different classic car subframes and steel wheels. For me,this is the best and most durable solution.

Probably find it had some anti-static wires running from the wishbone to the chassis. A lot of the Wedges do.

No, I don't know why either.

I wonder if someone has retro fitted brake wear indicators? Sierra and Granada had them and that looks like a handy place to put the wire clip.
