Galvanising A Chassis

[SubRosa]

Has anyone here had any experience with getting a TVR chassis Galvanised?

I know that each tube will need drilling to allow the Galv to flow through and to let the air/gases out. Did you lead plug it after, leave it open and have you had any cracking problems since?

Tis what I'll be doing when/if I get round to it.

Somebody posted quite recently that they'd had it done with no problems, but it's not generally considered a good idea because there is a substantial risk of chassis distortion.

Agreed. A better method with the same results is to have it shot blasted and hot zinc sprayed.

Then powder coated

Galv needs to many extra holes drilling in the chassis to drain and exhaust the gases etc, so it,s a no go.

As above. I work at a refinery in the South, and our inspection people are specifying 'thermally sprayed aluminium' for new fabrications. The product blurb guarantees a 25 year life cycle.

Had a few items in service for >5yrs and it looks promising re: service life.

All IMHO of course.
