Or get the chrome removed. Might be possible to submerse most of the frame and retain the chrome stays upon de-plating. You will need a co-operative plater.
...I'm prepared for all possible outcomes.

It is not something I had planned on investing heavily in. Worst case is I will end up stop drilling the cracks, fitting in a proper seat post, not go to all the work of a proper repaint, put it together with parts on hand, and see what happens. I guess I could go with a stainless hose clamp beneath the stays and below the cracks as a tacky accessory, but I am loathe to do that.
I don't much care about saving the frame chrome, and have been known to repaint chrome forks to match frame color.
