Do u need to block any k5la vents when powder coating?

From memory the the k5 has vents on the cap do they do anything? Also can u just use the bolts to chase out the threads or do I need a die?

I don’t know the exat function of the vents on the back caps, so I plugged them during painting. I also taped off the entire power chamber and mounting face for the back caps.

I know powder coat is a different animal, but…

Cheers I pluged the holes but just stuffed paper towel in end of the bells. Figured they would never be seen sprayed as far as I could inside.

I did mine gloss white, might paint the raised writing on the back of the caps black.
