Coating lead to aluminum 2

[RTXO]

I am trying to coat a thin layer of lead onto aluminum, to protect the aluminum from battery acid. Any suggestion on how.

'Tin' the aluminum with 90-10 (lead-tin) solder. Need a good flux, one specifically for aluminum.
Or, electroplate lead onto tin-plated aluminum.

I believe your best bet is to deposit a Zincate coating prior to any plating. Check with the any plating shops in your area. If you you Zincate the suggestion given by kenvlach will work much better.

Something like SurTec 652
