Bill, After many hours chasing many turn signal/stop light/running light problems in the past I would suggest you check all of your grounds. Didn't see bad grounds mentioned anywhere in the thread. That's always the first thing I check as it is very common, especially on a new install or new paint.

When a light circuit has a bad ground it will back feed into any other systems to find the easiest path to ground and causes some really strange things to happen.

Check each light, ensure your grounds are not insulated by corrosion or paint. Not saying this is your problem but easy to check.
