I am doing my first CPR PF swap, I've done one other cleared swap before so know the basics. I am using brand new dewalt brad points, etc.
I just started this and just by checking hole diameter managed to take clear off, and then my first attempt to clear out with the drill took off more. I am a little shell shocked here and not sure how to proceed.
As you can see many of the holes have paint and clear inside and a couple are painted/cleared over. Is that what is creating the weakness and causing it to chip like so? I was wondering if the lack of adherence for lack of a better term may be the cause. Any advice would be greatly appreciated.
