Primer to avoid top coat problems?

[67Dad]

To all of you seasoned restorers, what are the best primers (or a good way to pick a primer) to ensure compatibility with the possible top coat/clear coats? e.g. is there any compatibility issues with aftermarket parts that come primed, or with using a Dupont primer if you later wanted to use a PPG top coat, vice versa, etc.?

Thanks.

(We'll probably do the priming ourselves...haven't decided on the top coat yet and my do that with a pro or experienced amateur shop).
