Properly painting the short block

Guys I'm curious the approach you have used with success. I'd like a durable paint finish for the short block that withstands chipping and peeling. The problem areas in my experience have been next to the timing cover, and around the distributor. It always seems like these areas just chip and flake, expecially when pulling some of these parts. Like if you pull the timing cover and gasket it seems to just tear the paint right off. And that's a proper pain in the butt cleaning up and repainting. Especially if you have a raw aluminum finish on the timing cover.

I've used por15 engine paint in the past and had these results. Super clean prep work, laquer thinner cleaning, spraying the por15 on etc. I understand the basic fundamentals of painting here. Looking for suggestions with experience to back up.
