Metal M4 receiver vs Baked Ceramic coating ?
I am presently in the process of having my metal KJW M4 receiver CNC engraved with Canadian C8 markings, and then I am planning to coat it with a bake on flat black ceramic coating. The '' HIC'' is that the ceramic coating requires the part to be put in the oven at high temperature and I am not sure how tolerent is the aluminum receiver to temperature. I wish not to warp or crack it. Have anyone did this before ?
