I was building a new lower today and I accidently scratched some of the black finish off my stripped lower putting in the roll pin for the bolt catch. Since the lower is aluminum, is there a need to repair the finish? If I were to repair it, what is the best way to go about it?
Thanks. |

Scratches are only cosmetic, but as suggested, if it bothers you, birchwood casey alumablack is the stuff you want.
For future reference, use masking and/or electrical tape on your lower during assembly to prevent scratching, especially when installing the bolt catch pin. |

Quoted: The birchwood casey stuff works good. I used it on an aluminum gas block I had to file open because the slots were out of spec. The aluminum black stuff made it look almost perfect. It's a chemical, not a coating. Put it on, let it stain/soak, then rinse off. Is it that different than the B/C Super Black Instant Touch-Up Pen? I notice that the pen doesn't work all that well in itself. The flat black leaves a glossy puddle looking build up. I may be doing it wrong, but the pen coats with more of a paint. Suggestions? |
