This topic raised its ugly head again recently and reference was made to an earlier lengthy thread. All good advice.
I stumbled on this link and thought it would be useful. It actually quantifies the various noise found in the automotive power supply and offers useful suppression methods.
I don't know how available these devices are to hobbyists.
It also has useful insight into soldering techniques. Worth a look.
