Different PC Q

[gnappi]

I want to powdercoat an anodized aluminum slide mounted optical sight mount.

The issues are..

1. The mount has a dovetail which is inserted into the slide OEM sight mount and I want to mask off the sight mount dovetail. Best method? Hi temp silicone tape?

2. How can I block fine threaded screw holes? I was thinking of squirting silicone sealer but that would be a pain to remove.

3. How to PC over new anodizing? I read I can just clean and go?

I had a steel part that I wanted to partially PC (similar situation). I used a brush and brushed PC only on the surfaces I wanted and just put it in the oven that way. Worked fine

Might move this to the gunsmithing part of the forum. Not saying you have to but probably people who watch that section of the forum have more experience with non-lead metal finishes.

for the screw holes if you have extra screws could use the screw in the holes , just break them loose before the part cools down
