ᐅ Is it possible to paint titanium zinc and then apply gold leaf?

I want to build a small canopy roof that will be covered with metal sheets.
The dormer on the house has titanium zinc (titanium zinc sheet), so the canopy will use the same metal.
It might be gilded at some point in the future (if the upcoming lottery win needs to be stored or something 😉).
Gilding metal sheets requires a primer or base coat.
What I have learned is that gilding galvanized iron parts can be challenging, but it is possible.
Does anyone have more detailed information on whether titanium zinc can be successfully (and permanently) gilded?
For example, are there church roofs made of titanium zinc that are gilded?

Yesterday I contacted someone,
and they just replied very kindly.
Unfortunately, we have no experience with gilding zinc parts, as we do not gild zinc components ourselves. If a customer wants gilded elements, we produce these from stainless steel or copper if possible. The first important consideration is whether the gilding is intended for interior or exterior use.
Another point to consider is the method you want to use for gilding. I believe the traditional mechanical methods, such as oil gilding or Instacoll gilding, are not recommended because zinc tends to outgas easily, causing small bubbles to form under the gold layer, which eventually causes it to peel off. You might try a chemical method, like electroplating, but as mentioned, zinc is quite sensitive to various chemicals, so success is not guaranteed.

I think the key issue is the subsequent gilding on the roof, which prevents proper processes like galvanizing. Regarding the comment about the seam, one could try dismantling everything, then gilding it, and putting it back on the roof.
Wouldn't a gold-effect paint work?

Yes, the roof (approximately 3 sqm (32 sq ft)) will be constructed from wood, covered with titanium sheet metal, and may be gilded later—perhaps after a few years...
but as I said, I am currently revising the plans...
A gold effect paint is possible, of course, but that looks quite different from real gold...

Paint can prevent that – and you need paint anyway for leaf gilding.
But only very specific paints adhere to zinc. (Most just peel off again)
Whether any of those also prevent potential zinc damage, I just don’t know. In my opinion, zinc sheets are powder-coated and then baked on. This should also work with gold paint. Trial and error will teach you.
