Galvanised Subframe..

[abr33]

Hi all, thinking the other day, my subframe paint on my 33 is looking a bit ordinary, flaking off etc.. So, i have to obviously sandblast it, and rather than pay a hundred bucks or more for a good respray, why not galvanise it? would cost me about 60 bucks, never come off, make cleaning easy, and be different.

And while im at it why not do front crossmember too?

Only consideration is id need to hardness test the metal to check its not a high carbon material (unless someone knows?) because it will be heated to about 700 degrees and that will damage or soften some metals.

Anyone got some input?

yeah i'd say its far to hot for it. you will run the risk of deforming it.

powdercoat?

Im not too worried about deformation, its a pretty solid structure, more so in denaturing the metal and softening it. ill test it soon for hardness. Powdercoating wont get inside properly and will be expensive. all else failing ill respray it myself, just like the idea of gal.. might be onto a good thing

Or it might be a total failure... ill try source a second cradle so if i screw it, it wont matter

if you're talking about hot dip galvanizing then no way.

You have a chance of warping or worse from the heat if it's not done properly, plus it will add a lot more weight than just powdercoating, as your basically covering the whole thing with a thick layer of zinc.

I used to work in hot dip galvanzing a long time ago, and there is no way i would ever put anything of my car through the acid/hot dip/quick cool process.

Yeah i know its not ideal for a structure like it, but iv sent alot of even lighter things down and got done.. and it would add a couple of kgs... it was just a thought, i can get the blokes to do it a special way if need be and slow cool
