I do have some corrosion experience, rebuilding a 70 year old truck and all!. Had not thought much about aluminum to painted metal contact, but I can easily put some of that paint protective plastic film between pieces. Thanks
Kind of OT for this thread, thinking about making door cards with this pattern:
I think black is out for the color, looked good in sunlight but it just disappears inside the cab where I already have too much black.
The other sample is aluminum. I'm finding it a bit to shiny although it does not show much glare in the picture here.
The back of the black piece is the satin of new steel sheet, did not take a picture, but I keep looking at that side and thinking maybe a dull silver paint. Then I could do the piece on dash that hides stereo and the center of glove box beads to match.
