I haven't checked this thread for quite a while... but any way as for the results, we tried it and it can be done.
We started with a pile of prepped AR magazines and tested the process with both H series and C series Cerakote. We tried the H series in various stages of "cure" from tacky (from 15 minutes in the oven) to allowing it to air dry. Without going through all the boring details, we were able to dip to H series by removing it from the oven while the coating was tacky and dipping it immediately then baking the product. Once baked, Micro Clear was applied. Honestly, it's a pain in the ass and we decided to dip to Duracoat and then use a Cerakote clear.
Perhaps some of the scientists out there will come up with a more reliable process.
The last gun that we dipped with a Cerakote clear is a competition 12ga for a customer that block shoots. There's some pics on our FB page, Full Bore Firearms.
