Watchin wheeler dealers about a morgan and they got a galvanized chasis an was thinking would that be better for keeping rust at bay than powercoating

I know its only in grey but if that means theres no rust for a long time its work it

[waddle]

id guess so , just because it wont chip like powder, thats not based on any knowlage by the way, just my 2p , only downside being you widhave to scrape off the galv or powder to weld, id just go with loads of paint , and work touching it up into your mantinance scedual

why would you have to weld it if you have had it galvanised??? and i am going to get my subframe galvenised on my project car but i am also going to paint it black so that it wont actually look like it has been galvenised.

[waddle]

if it starts to go again or you scrape it off

[03jkirk]

with a galvenised subframe its not gonna begin to rust for a considerable amount of time, you have to remeber how long many subframes actually lasted on production minis and they were only painted so i highly doubt theres much chance of the subframe rustin be4 any other parts of the car and will be much less labour intensive than repeatedly paintin the subframe

aha i get that itll take ages to rust whatever you do , was just trying to weigh them up, and also depends how often you have your front end off etc, slapping on a bit of stone chip and hammerite isnt any hardship realy

he must drive very very carfuly !

Youd think so but he drive crazy sometimes haha, hes 70 , 850 engine and shows us 1275 lads up in the corners he dont half throw it around, well looked after though, raduis arm bearings greased very regularly

[03jkirk]

shows how a lil care goes along way with older cars

[waddle]

true , look after it and itll look after you , even if you do thrash it

I'm sure from what I have read on this forum and this subject, that galvanising will twist warp a subframe, unless you put it in a jig to prevent this, I could be wrong and I'm sure someone will confirm soon enough

[tiger99]

I am not convinced that it will distort during the galvanising process. The company doing the galvanising will be able to advise.

[oliver122]

people have had subframes galved and in some cases it did distort but others its turned out fine , take it somewhere that does chassis ect would be your best bet, as they will know how to deal with items that could twist best

I was looking into getting my subframes powder coated. I think galvanised metal does still rust, but is it called white rust? Which happens If not painted or coated. I think it's something to do with the zinc it's dipped in. Which also makes welding a bit more tricky due to the smoke and fumes when welding galvanised.

It's very early and don't really know what I'm on about, so I could be completely wrong haha
