Thread: Getting a chassis galvanised in Brisbane

The Army must have changed their tolerances since I was in....

Hello again - sorry for the delay as I hadn't noticed the question until now.

I didn't get either the chassis or firewall treated - so, can't give an answer.

What was treated - about 80 parts - came up quite well.

Cheers,

Neil

As V8Ian says, spray on zinc rich coatings are a safer bet. Modern zinc based coatings are very tough and give excellent corrosion protection.
Also keep away from the surf driving so loved by advertising agencies!!
Galvanizing box section steel structures is a very specialised task.

"the military" didn't build the perentie so what would some dude who "worked in the military" know about this? Not saying he didn't tell you this, but there is absolutely zero likelihood that this is true. Thousands of boat trailers are galvanised every year, you're telling me every second one is bent and unusable?

If the company doing it heats the chassis before dipping, less distortion will occur.
I toyed with the idea of getting my S3 SWB done. Decided against it after I had my 5 rims done but I should have checked them for roundness before sending them off.,
I think the Brisbane factory they went to has closed down.
Rims were $12 each, chassis being around $220.

I had a set of series rims sand blasted and hot zinc sprayed about 12yrs ago, every one of them has rust stains coming from the seams. Not a lot, but it is there. These are rims that have never been on a car, just in dry storage. I wouldn't bother with it again, just paint would have been as good if not better.

Inorganic zinc coating is totally different to hot zinc spraying.
