Very nice bolts.

Someone was advising me to not use stainless bolts when putting my rocker panels back on. They said that the difference between two different metals (stainless and the car's own steel) would cause corrosion.

Any chemists out there that can confirm or deny that?

e) Contact corrosion
Contact corrosion is a very common form of corrosion that develops when metallic materials with different electrochemical potentials physically touch each other in the presence of an electrolyte. In this situation, the lower-grade metall will be attacked by the electrolyte and will go into solution. The extend of the corrosion depends on the strength of the current in this galvanic cell.
We encounter contact corrosion very often. A commonly known example is the connection between steel and stainless steel flanges.
Contact corrosion is also common when cast flanges are attached with stainless steel screws.
Contact corrosion can be prevented or reduced by insulating the metals at the points of contact, by keeping electrolytes away from the metals (move contact areas into dry environments), through constructive measures that avoid contact between cathode areas and very large anode areas.
