Chutney for gifts -- need to protect from metal lid?

[sarosenthall]

Hey, I made this great chutney for Christmas gifts. The recipe says to not let the chutney touch metal (of the lid of the canning jar). I assume this is because of the vinegar in the chutney interacting with the metal of the canning jar lid? But these canning jar lids I got (just the regular Kerr ones at the grocery star), the lids have a white coating (some kind of paint) covering the brass metal that the lid is made of. Does this mean I can just go ahead and put the lids on and it will be OK? Or do I need to put a piece of plastic wrap on top of the chutney, before putting on the lid?

Tried calling the company but their line is busy busy busy.
thanks, Susan
