Dang! How do you fix the little cracks and casting boogers in Magnesium before you coat them? I can see why you wouldn't want to do any more. Imagine if that set was a REALLY good pair!! :eek:
Most coaters use endless layers of primer and cover up defects. I learned long ago that took longer and gave substandard results so I do bodywork on literally every part that crosses my bench. Aluminum is my favorite, and intakes hold a very special place in my heart.
Mag can tear up my carbide bits but are generally the best method of attack, along with smoothing / feathering edges with riffler files and sanding. Most mag castings have too much metal and overflow the molds but these were missing a lot instead. The factory had a $hit ton of paint to cover it all up.
