Help freeze plugs and cam plug leaking

I completely rebuilt this motor and spent some generous time repairing all the plug hole surfaces since they had ALL been marked at 3 points with a center punch likely. I first assembled the motor using the steel narrow lip freeze plugs and I applied shellac to the surface. Well I'm sure you can imagine how that worked out. So I went back and replaced all the plugs using brass plugs, again further repairing the surface but being careful not to go hog wild and risk making the hole out of round. I once again used shellac and low and behold 3 of them still weep. My rear cam plug is leaking as well. Not sure I installed it facing the right direction honestly. Any tip and suggestions welcome. I am getting frustrated with this darn motor. For the first time in my life am I considering using rubber plugs. I live in south Texas and the car would never be exposed to extreme weather. I just hate the way it would look. Thanks in advance as always!
