Here is the reply from Zinga California I received, it is getting us closer to the answers we need it is sounding better I have cut and paste the correspondence today, sounding better as we go.
Hi Skip,
Thank you again for the email.
Topic 1... You would want to have ZINGA in contact with the bare metal, otherwise you wouldn't get any cathodic protection. If you could provide exactly what type of automotive paint you are using, I can answer the question regarding top coats specifically.
Here are some general guidelines...
Topcoats to avoid using in conjunction with ZINGA include all alkyd-based enamels, which must never be applied over any zinc based coatings. This is because the zinc reacts with the alkyd and causes saponification which allows the paint to dry but to never harden and cure.
High-build vinyls as well as acrylated and chlorinated-rubber enamels are extremely high in solvent content, so the use of a sealer is mandatory with these coatings. ZINGA recommends the use of water-based topcoats to complement the environmentally friendly properties of ZINGA. Alufer N is widely used to seal the ZINGA prior to the application of topcoats.
It should be noted that cellulose lacquers cannot be applied directly onto Zinga, as the esters they contain will attack the binder. 2K automotive primers must be applied onto the Zinga layer beforehand, and then virtually any topcoats can be used.
Topic 2... ZINGA is weldable. ZINGA coated steel can be MIG or arc welded to x-ray standard, with no porosity in the welds.
For purchase, right now everything is purchased through our corporate offices in Buffalo, NY.
Here is a link to the sizes that are available:
