 Best finish/coating to protect AR lower

Doing a couple of builds and I'm looking for a finish/coating that will protect my lower from corrosion and help em stand up to hard use.

A couple years back I had a couple of lowers cerakoted and I was not impressed. After working the action/ charging handle a half dozen times, it sliced through the cerakoting to bare metal (and a lot). Not exactly confidence inspiring. One of the receivers later got pitting. ????? Kept in the safe, cool and dry.

What other finishes/coatings are available for my needs?

Something wrong with the milspec anodizing?

Something like Moly Resin over the anodizing would just add more protection.

If you're building 80% receivers or something and not anodizing them, nothing else is going to help you all that much.

What about nickel boron or NP3 plus?

We only use CeraKote, GunKote, and DuraCoat. I did some pretty extreme testing on each of them before we started applying them. Each has their strength and weakness. So I cant make an informed judgement on other coatings. Any of the thermal coatings will give you a great looking long lasting finish.
